open tube of blood
Jun 9, 2001

how long would the hiv virus live in an open serum tube used in a laboratory? is the risk lessened if the blood is spun down and the contact is with the serum or plasma vs. the whole blood?

Response from Ms. Breuer

Your question leaves out the key information: has the blood come into direct contact with a break in the skin or a mucous membrane? If not, there is no exposure. If it has, there is a potential exposure and the only truly reassuring answer is an HIV test. Serum or plasma is far less likely to be infectious than whole blood, but not risk-free. The test is the answer.
