Accurate automated leucocyte differential counts despite profound leucopenia.

Accurate automated leucocyte differential counts despite profound leucopenia.

The differential white cell counts produced by the Technicon H*1 Autoanalyser in profoundly leucopenic specimens were compared with those carried out by manual differential counting by light microscopy of peripheral blood smears stained with May-Grünwald-Giemsa stain. The correlation achieved allowed the H*1 derived differential count to be reported with confidence.

Automated differential leukocyte counts.

Automated differential counts have the advantage of precision, efficiency, safety, and economy. They could potentially serve effectively in 90 percent of patients with normal counts or in 75 percent of patients with anemia only (64 percent of the total in this study). Even patients with increased white blood cell counts and major population shifts (toward granulocytes or lymphocytes) could be f...

Platelets and leucocyte counts in pregnancy.

A study involving the obstetric clinic population of 3 major teaching hospitals of Karachi has been conducted to define changes in leucocyte and platelet counts as pregnancy progresses. 573 "normal" pregnant women--183 in the first trimester, 195 in the second trimester and 194 in the third trimester were included in this analysis. We have found leucocytosis to be a feature of normal pregnancy;...
