CRP analysis will be performed during the consultation in accordance with the manufacturer's instructions. The Afinion™ CRP Test Cartridge consist of a 1.5 µL glass capillary to be filled with blood from a finger prick and a reagent container. First, the sample is automatically diluted with a liquid that also lyses the blood cells. If the sample is whole blood, the haematocrit value is estimated from transmission measurement of the haemoglobin. In this case, the measured CRP value will be automatically corrected according to the sample's haematocrit (Hct) level, and the result is displayed as the serum-CRP concentration.
