Manual Differential Cell Counts Help Predict Bacterial Infection

Hematopathology / ELIMINATION OF REFLEX MANUAL DIFFERENTIAL COUNTS

Automated peripheral blood leukocyte differential counts (LDCs) are widely accepted in routine practice. However, many laboratories still reflexively perform manual LDCs based solely on abnormal automated results or instrument “flags,” before any manual triage step. We describe our transition to a procedure that uses manual methods to validate, rather than to replace, automated LDCs (an approac...

A Multiple Manual Register for Differential Leucocyte Counts.

Evaluation of total and differential white blood cell counts in workers exposed to lead

Introduction: Lead is a toxic heavy metal that has adverse health effects on blood parameters. About 80% of lead produced is used in batteries, especially vehicle batteries. Therefore, the present study aimed to assess the hematological changes, including total and differential white blood cell (WBC) counts in battery workers exposed to lead, and compare with the non-exposed group. Materials a...

Some factors affecting bacterial colony counts in urinary infection.

Normal laboratory values for differential white cell counts established by manual and automated cytochemical methods ( Hemalog DM ) 1

sYNopsis The central 95 percentile estimates of the normal white cell types (as determined by a standard differential count) were calculated from 777 normal individuals. The results were divided into groups by age and sex and expressed both as percentages and as absolute numbers of cells. A similar survey was made using the prototype of a new automated differential counting method (Hemalog-DTX)...
