Platelets (PLT) Platelet count (PLT) Hemoglobin count (Hb/HGB) Hematocrit (HCT/PCV) Platelet count (PLT/PC)

In addition to these, there are some other parameters of the erythrocytes: Mean corpuscular volume of erythrocytes (MCV) Mean corpuscular haemoglobin volume of erythrocytes (MCH) Mean corpuscular haemoglobin concentration of erythrocytes (MCHC) Red cell Volume distribution width (RDW), etc. By observing the changes in the number and morphology of the distribution, to determine the disease is one of the doctors diagnosis of the condition of the commonly used auxiliary means of examination
