Why were my results reported as having a clotted sample?

Blood clots in sample tubes commonly occur when the sample has not mixed correctly with the  anti-clotting agent in the sample tube, or for it to have clotted during transit. It does not indicate any health problem or risk. 

This occurs occasionally due to the nature of biological specimens but it does mean that the analysis of your tests may not be possible. In this case, we are able to offer you a repeat test at no charge.

To help reduce the risk of clotting please take extra care to mix sample tube(s) thoroughly, but gently, after collection. The tubes need to be inverted at least 10 times to stop the entire clotting mechanism.

You should also ensure to take your sample between Monday to Thursday, then post on the same day in the prepaid mailbag included. This ensures the laboratory receive & process the freshest sample possible.
