Change of blood bottle for serum progesterone

Blood samples for serum progesterone analysis must now be collected into a red top bottle (clotted serum).

Studies suggest that storing progesterone samples in gold top gel barrier bottles for prolonged periods can produce falsely low results.

Gold top samples received after 1st April 2022 will not be accepted for analysis.
