THE national blood supply remains safe despite a recall of some chemicals used to test donated blood for the human immunodeficiency virus (HIV) and the hepatitis B and C viruses, the Health Sciences Authority (HSA) has said.
No tainted blood sample would have slipped through and be used undetected because all samples would also have been put through another test using chemicals unaffected by the recall, it added.
This other test is a compulsory standard for all international blood service providers, whereas the test using the affected batches of chemicals was an optional one used as 'an additional safeguard', it said.
