ABSTRACT:
A presealed integral hematocrit test assembly includes a holder, a bore molded into the holder, and a blood sample tube mounted on the holder adapted to receive a sample of blood by capillary action, whereby the blood sample tube is filled with blood from its inlet end by capillary action, and the test assembly is centrifuged into a column having a red corpuscles portion, white corpuscles portion, and a plasma portion. The method of using the presealed integral hematocrit test assembly includes the steps of measuring the length of the red cells column portion and measuring the total length of the blood column, and dividing the length of the red cells column portion by the total length of the blood column to make the hematocrit determination.
