Blood Sample Clotted

Blood Sample Clotted - A retrospective, observational study to evaluate interventions to reduce blood sample clotting. Clotting (also known as coagulation) is when your blood turns from a liquid to a gel. Inadequate mixing of the tubes. Blood clots in sample tubes commonly occur when the sample has not mixed correctly with the clotting agent in the sample tube, or for it to have clotted during transit. This guideline describes which coagulation tests can be assayed using capillary samples. Coagulation tests must be performed on samples taken by clean venesection, and filled to the appropriate level (in line with black arrow). Mix blood immediately after collection. It does not indicate any health problem or risk. For example, for a short time before some tests, you may need to: Web venous blood samples can be difficult to obtain from children and the alternative method of capillary blood sampling using a thumbprick or heelprick are often used at sc(nhs)ft for basic haematology and biochemistry tests.
