Detailed explanation-1: -definition. A differential blood count is the percentage of each type of white blood cell per 100 white cells counted; the white cells of a normal adult are about 55 percent neutrophils, 30 percent lymphocytes, and small percentages of eosinophils, basophils, and monocytes.
Detailed explanation-2: -Normal Results Neutrophils: 40% to 60% Lymphocytes: 20% to 40% Monocytes: 2% to 8% Eosinophils: 1% to 4%
Detailed explanation-3: -To determine the differential, a drop of blood is thinly spread over a glass slide, air dried, and stained with a Romanofsky stain, most commonly the Wright or May-Grunewald-Giemsa technique. Two hundred cells are then counted and classified.
Detailed explanation-4: -What Is a Manual Differential Blood Test? Most differentials are automated tests done with special equipment. If something unusual shows up in an automated test, the lab might manually check the sample. This is called a manual differential. It can also help look for unusual cells and young cells called a band.
