Materials and Methods: Blood samples have been collected from a sample size of 50 patients randomly from a dental institutional laboratory. Anticoagulants are used to prevent the blood from clotting. The RBC size is calculated by using a standard formula from the peripheral smear of the obtained sample. MCV is obtained from the laboratory by using automated hemology analyser. Results are analysed statistically.

Results and Conclusion: As the study states the method of RBC size calculation by using the peripheral smear alone and compared to the MCV values, a pathologist can very well analyze the macrocytic RBCs or Microcytic RBCs without an automated analyzer and there is no need of searching and comparing the size of small lymphocytes. A need for scale (in-built Vernier caliper) in the microscope which is useful for the RBC size analysis and it is also a time-saving method. This study concludes that a linear relationship between the RBC size and MCV statistically.
