Reticulocytes are the cells at the stage between normoblasts and mature red blood cells (RBCs). Unlike normoblasts,
they are nonnucleated; however, they do contain remnants of RNA in their cytoplasm. They are produced in the b
WBC Differential Count
This experiment is for determining the percentage of each WBC (neutrophil,
lymphocyte, monocyte, eosinophil and basophil) in a blood film.
Count 100 WBCs using bright field microscope at 40 or 100 magnification.
Hb (g/dL) = A x 29.3
PCV (%) = (RBC volume whole blood volume) x 100
No. of RBCs in 1L of whole blood (cells/L) = N x 10000
No. of platelets in 1L of whole blood (cells/L) = N x 10000
MCV (fL) = (PCV RBCs) x 10
MCH (Pg) = (Hb RBCs) x 10
MCHC (g/dL) = (Hb
White blood cells (WBCs) are a huge part of the bodys immune system. They help protects us against
foreign organism invasions, allergy and they produce antibodies.
If WBC levels drop (i.e. our immunity weakens), we are in greater risk

RBC count is used to tell how many RBCs there are in the blood and is normally used as part of the complete blood
count (CBC) along with PCV and Hb, and can help in finding red cell indices. RBC count is also a screening test for
