CHEMICAL AGENT FOR EASILY MEASURING NUMBER OF BLOOD PLATELET IN BLOOD SAMPLE

摘要

An agent for facilitating the counting of thrombocytes in blood samples in the presence of erythrocytes, comprises an aqueous solution of mercuric chloride in a concentration of between 1.2 and 4.0 g/l. The pH of this solution is adjusted to 1.5 to 4.8, preferably by the addition of hydrochloric acid or nitric acid or mercuric nitrate. 2 mls of this solution is mixed with 20 mu l of the blood to be tested. The erythrocytes are decolored in this solution and the thrombocytes become more brilliant in the microscopic image so that they are relatively easy to count.
