What is Tua lanh?

According to the provisions of Clause 1, Article 34 of Circular 26/2013/TT-BYT, it stipulates the issue you are concerned about. To be specific:

Cryoprecipitate is a preparation separated from the precipitate formed during the thawing process of fresh frozen plasma at temperatures of 10°C or lower. Cryoprecipitate can be further refined and virus-inactivated by chemicals or temperature.

Thus, cryoprecipitate is one of the blood-derived preparations.

In addition, the Circular also stipulates the standards and quality of cryoprecipitate as follows:

Standards and quality testing: Conduct quality tests (with a random sample size from 0.1% to 1% of the total number of units prepared, and not less than 05 units per month) on the following standards:

- Volume from 10 ml to 25 ml for each cryoprecipitate unit derived from a whole blood unit with a volume of 250 ml or greater. Volume from 80 ml to 120 ml for each pool of cryoprecipitate from 2,000 ml of whole blood. The actual measured volume of cryoprecipitate should not differ by more than 15% from the volume stated on the label.

- Factor VIII concentration not less than 30 IU for each cryoprecipitate unit derived from a whole blood unit with a volume of 250 ml or greater, and at least 75% of the samples tested must meet this standard;

- Fibrinogen amount not less than 75 mg for each cryoprecipitate unit that is non-virus-inactivated, derived from a whole blood unit with a volume of 250 ml or greater, and at least 75% of the samples tested must meet this standard;

- No abnormal coloring, no cloudiness, clots.
