Part II. Specific Provisions

1.

Whole Human Blood

Whole Human Blood is blood which has been mixed with a suitable anti-coagulant, after collection from a human subject in normal health.

The blood shall not be obtained from a human subject:

(a): who is known to be suffering from or to have suffered from syphilis or hepatitis,
(b): whose blood has not been tested with negative results for evidence of syphilitic infection, or
(c): who is not, as far as can be ascertained after medical examination and the study of his antecedents, free from disease transmissible by blood transfusion.

The blood shall be withdrawn aseptically through a closed system of sterile tubing into a sterile container in which the anticoagulant solution has been placed before the container is sterilised. The equipment used must be pyrogen-free. When withdrawal is complete the container shall be immediately sealed and cooled to 4° to 6° C and not opened thereafter until immediately before the blood is to be used.

The blood will be collected into a citrate solution of acid reaction containing dextrose. No antiseptic or bacteriostatic substance shall be added. The volume of the anticoagulant solution must not exceed 220 ml per litre of the Whole Human Blood and the haemoglobin concentration must not be less than 97 gram per litre.

Blood Group — The blood group under the ABO system shall have been determined by examination of both corpuscles and serum and that under the Rh system by examination of the corpuscles, using a separate sample of the donor's blood. When there is a national standard, or nationally recommended technique of blood grouping, that technique shall be used.

The term Rh negative is only to be used when specific tests have shown the absence of the antigens C, D, D^u and E. All other blood must be labelled Rh positive.

Blood exchange under this agreement should only be used for recipients of the corresponding ABO group.

Storage — Whole human blood shall be kept in a sterile container sealed so as to exclude micro-organisms and stored at a temperature of 4° to 6° C until required for use, except during any period necessary for examination and transport at higher temperatures, any such period not to exceed thirty minutes after which the blood must immediately be cooled again to 4° to 6° C.

Labelling — The label on the container shall give all the information shown on the model label (Annex 2). The Rhesus group shall be written as ‘Positive’ of ‘Negative’ or, in abbreviated form, ‘POS’ or ‘NEG’.

1.bis.

Human red cell concentrate

A human red cell concentrate is a unit of Whole Human Blood from which most of the plasma has been removed.

It contains most of the red cells of the unit from which it has been prepared; other cell components may be present or may have been partially removed.

The liquid content of the concentrate will consist either of the residual plasma, or of an appropriate isotonic artificial aqueous solution added after the plasma was removed. The volume of red cells should constitute between 65 and 75% of the total volume of the product, but if a greater red cell concentration is applied the approximate percentage of erythrocyte volume (haematocrit) shall be indicated on the label.

All operations required in the preparation shall be carried out under aseptic conditions: decantation shall be carried out using a sterile, closed system and by compression only. No antiseptic or bacteriostatic agents should be added.

Blood group and storage — as for Whole Human Blood.

Labelling — The label on the container shall give all the information shown on the model label (Annex 2bis). The Rhesus group shall be written as ‘Positive’ or ‘Negative’ or, in abbreviated form, ‘POS’ or ‘NEG’. If an artificial aqueous solution has been added, the label shall also indicate its volume and composition.

2.

Dried Human Plasma

Dried Human Plasma is prepared by drying the supernatant fluids which are separated by centrifuging or by sedimentation from quantities of Whole Human Blood.

During preparation no antiseptic or bacteriostatic or other substance shall be added. Dried Human Plasma shall be obtained by freeze-drying or by any other method which will avoid denaturation of proteins. The dried product shall be readily soluble in a quantity of water equal to the volume of the liquid from which the substance was prepared. The protein concentration of the solution thus obtained must not be less than 45 gram per litre, and must not show visible evidence of the products of haemolysis. The haemaglutinin titre shall not be greater than 1:32.

Dried Human Plasma prepared from one or two donations of blood

Donations shown to contain dangerous levels of iso-haemolysins (determined using a sample of fresh serum) or any immune haemaglutinins shall be excluded. Unless the plasma is pooled and frozen within 48 hours of collecting the blood, the sterility of each unit shall be tested by culturing not less than 10 ml.

Dried Human Plasma prepared from pools of more than two donations

Pools shown to contain dangerous levels of immune haemaglutinins or of iso-haemolysins shall be excluded. To avoid untoward effects due to the products of bacterial growth in the plasma no individual donation shall be used if there is any evidence of bacterial contamination, and the sterility of each pool shall be tested by culturing not less than 10 ml. To minimize the risk of transmitting serum hepatitis, plasma should be prepared from pools which should contain not more than twelve donations, or by any other method that has been shown to diminish the risk in comparable manner.

Solubility in water — Add a quantity of water equal to the volume of the liquid from which the sample was prepared; the substance dissolves completely within 10 minutes at 15° to 20° C.

Identification — Dissolve a known quantity of the product in a volume of water equal to the volume of the liquid from which it was prepared; the solution passes the following tests:

(i): by precipitation tests with specific antisera, it must be shown to contain only human plasma proteins;

Annex 11. Freedom from toxicity of plastic blood transfusion equipment

to the Protocol Council of Europe European Agreement on the Exchange of Therapeutic Substances of Human Origin

I. Chemical tests

The tests are intended to be applied to plastics blood transfusion equipment. This equipment consists of two main categories:

(1): plastics containers for the collection, separation and storage of blood and blood products;
(2): plastics sets for taking and giving blood.

The tests shall be carried out on the materials after they have been sterilised by the method to be used in the final sterilisation of the equipment. These materials shall include:

1): the plastics used to make the containers,
2): the tubing used in the containers and
3): the blood-taking and giving sets.

The tests on containers shall be carried out before the containers are filled with anticoagulant solution. However, if the tests are carried out on containers which have been filled with anticoagulant solution, the limit tests in Section III on the anticoagulant solution itself shall be taken into account when evaluating the results of the tests on the container.

The manufacturer of the transfusion equipment is required to disclose to the appropriate health authority the detailed formulations of the plastics material or materials and other materials used in the manufacture of the equipment, the source of the components of the material or materials and their methods of manufacture (or alternatively, the compound reference numbers), details of manufacture of the equipment, the nature of any processing additives and adhesives and the method of sterilisation. No change shall be permitted in any of the foregoing without prior submission to and approval of the appropriate health authority.

Each batch of raw material used in the manufacture of the equipment shall be identified by a batch number, which shall be recorded by the manufacturer of the equipment together with the identification numbers of all batches of transfusion equipment made from it and the results of all tests relevant to these batches.

Every practicable precaution must be taken to reduce the risk of adventitious contamination at each stage of the manufacturing process.

A. Preparation of extract and blank

(a): A total test as described below requires 1250 cm² plastics (total surface area, both sides, of a plastics sample in sheet form with surface area of 625 cm²). The sample — without any printing or label on it — should be cut into pieces of not more than 10 cm².
For tubing the length (L) in cm is calculated as follows:
L = 1250/(3,14 (D₁ + D₂))
D₁ = inner diameter in cm
D₂ = outer diameter in cm
The tubing should be cut lengthwise into sections measuring approximately 10 cm. For the extraction 10 ml of water is used per surface area of 50 cm².
(b): The pieces of plastics film or tubing should be placed in a container of borosilicate glass with 250 ml pyrogen-free distilled water obtained from an efficient still having glass condensation surfaces and collecting tubes.1. The opening of the container is covered with an inverted beaker and the container is then heated in saturated steam at 110° C for 30 minutes (autoclaving) and then quickly cooled to room temperature and the volume adjusted to 250 ml with pyrogen-free distilled water. It is of no significance if the plastics specimens tend to stick together slightly.
Heat-sensitive plastics material, instead of being heated in an autoclave, may be heated at 70° C for 72 hours.
A blank preparation is made in a corresponding manner omitting the plastics.

B. Tests on the extract

1.

Oxidisable matter

To 20 ml of the extract in an Erlenmeyer flask of borosilicate glass add 20 ml of 2 millimole potassium permanganate solution per litre and 1.0 ml of 1 mole sulphuric acid per litre and boil the mixture for 3 minutes. Cool the solution rapidly and add 0.1 g of potassium iodide and 5 drops of starch solution. Titrate with a solution containing 10 millimole sodium thiosulphate per litre. At the same time carry out a blank titration. The difference in the volume of thiosulphate used in the two titrations does not exceed 2.00 ml a solution containing 10 millimole sodium thiosulphate per litre.

2.

Chloride

The extract complies with a suitable limit test for chloride equivalent to not more than 11.2 μmole chloride per litre.

3.

Ammonia

The extract complies with a suitable limit test for ammonia equivalent to not more than 120 μmole NH₃ per litre.

4.

Phosphoric Acid — Phosphate

The extract complies with the limit test for phosphate.

Limit test for phosphate

Evaporate 25 ml of the extract almost to dryness in a Kjeldahl flask, cool the residue, add 2 drops sulphuric acid and 1 ml nitric acid, heat the mixture until white fumes appear, then cool. Add 1 drop of perchloric acid and heat gently for half an hour. Cool the residue and add water to 25 ml. Transfer 10 ml of the solution to a 25 ml titration flask, add 8 ml ammonium molybdate-sulphuric acid solution and 2 ml of freshly prepared solution of ascorbic acid, having a concentration of 100 g/l. Heat on a water bath at 50° C for thirty minutes, cool and dilute the mixture to 25 ml. The green or blue colour of the solution is not more intense than that obtained by treating 25 ml of the blank solution in the same manner.

5.

Acidity or alkalinity

10 ml of the extract is not coloured red on the addition of 2 drops of phenolphthalein solution and requires not more than 0.4 ml solution containing 10 millimole sodium hydroxide per litre to produce a red colour. After removal of the colour by the addition of 0.08 ml solution containing 10 millimole hydrochloric acid per litre, the addition of 5 drops of methyl red solution produces a red or orange-red colour.

6.

Residue on evaporation

Evaporate 100 ml of the extract to dryness on a water bath and dry at 105° C to constant weight. The residue weighs not more than 5.0 mg.

7.

Clarity and colour

The extract when viewed through a thickness of 5 cm is clear and colourless when compared with the blank.

8.

Taste and smell

The extract compared with the blank is odourless and tasteless.

9.

Special elements

The extract complies with suitable limit tests for

(i): any of the following elements: arsenic, chromium, copper, lead, silicon, silver and tin, equivalent to 1 μg/g
(ii): cadmium, equivalent to 0.1 μg/g

10.

Residue on ignition

1.0 g of the plastics material when ignited to constant weight leaves not more than 1mg of residue.

11.

Heavy metals

Dissolve the residue on ignition in the minimum quantity of a solution of 2 mole hydrochloric acid per litre, heating if necessary. Carry out a suitable limit test for heavy metals. The plastics material complies with a limit not exceeding 5 microgrammes per gramme as calculated as Pb.

Appendix

Biological test: limits and methods

A. Test for undue toxicity

(See Item II, 1 of Annex above): limit as specified in national pharmacopoeia.

B. Test for freedom from pyrogens

(See Item II, 2 of Annex above): limit as specified in national pharmacopoeia.

C. Test for haemolytic effects in buffered systems

(See Item II, 3 of Annex above):

(a): Limit:
A salt solution equivalent to a solution containing 5.0 gram NaC1 per litre, in so far as electrolyte osmotic action is concerned, shall not produce a haemolysis value higher than 10% and a salt solution of 4.0 gram per litre shall not differ by more than 10% in haemolysis value from that caused by the corresponding control solution.
(b): Method:
From the primary buffer stock solution for haemolysis three solutions are prepared: 30 ml buffer stock solution and 10 ml water (solution a₀), 30 ml buffer stock solution and 20 ml water (solution b₀) and 15 ml buffer stock solution and 85 ml water (solution c₀).
To each of three centrifuge tubes (1, 2 and 3), 1.40 ml extract are added. To tube 1 is added 0.10 ml a₀, to tube 2, 0.10 ml b₀ and to tube 3, 0.10 ml c₀, thus obtaining salt solutions equivalent to solutions containing 5.0 (tube 1), 4.0 (tube 2) and 1.0 gram NaC1 per litre (tube 3) in so far as electrolyte osmotic action is concerned. To each tube is added 20 μl fresh, well mixed heparinised human blood. The tubes are put into a water bath at 30° C (± 1° C) for 40 minutes. Then three solutions containing 3.0 ml a₀ and 12.0 ml water (solution a₁) 4.0 ml b₀ and 11.0 ml water (solution b₁), and 4.75 ml b₀ and 10.25 ml water (solution c₁) are prepared.
To the first tube is added 1.50 ml of a₁, to the second 1.50 ml of b₁ and to the third 1.50 ml of c₁. The tubes are centrifuged for 5 minutes at 2,000 to 2,500 rpm in a swing-out centrifuge. Concurrently, control solutions, in which the extract is replaced with water, are prepared for each of the concentrations.
The extinction at 540 nm of the liquid layer is measured. Buffer stock solution for haemolysis is used as blank. The haemolysis value in per cent is calculated according to the following formula:
(E_exp × 100)/(E_100%)
where ^E 100% = extinction for the solution containing an equivalent of 1.0 gram salt per litre
and ^E exp = extinction for the solutions containing an equivalent of 4.0 and 5.0 gram salt per litre respectively

Buffer stock solution for haemolysis

90.0 g sodium chloride, 13,7 g anhydrous disodium phosphate and 1.90 g anhydrous monosodium phosphate are dissolved in distilled water and made up to 1000.0 ml.
