Question 1

If the In-house Hematology Analyzer reports a total WBC of 45, 000 wbc /ul but Walker has 8 nRBC/100 wbc, what is his Corrected WBC?

Answer 1

CWBC = 45,000 x (100/8+100)
= 41,667wbc

Question 2

The obtained nucleated count must be corrected for the number of nRBC in the circulation.
To correct the “WBC” or nucleated count, the number of nRBCs per 100 leukocytes is recorded during the differential leukocyte count when performing a blood smear examination.
Then a correction is made as follows:

Answer 2

Corrected WBC = obtained nucleated cell count x [100 ÷ (nRBC + 100)]

Question 3

Formula used for WBC estimate:

Answer 3

Total/10 = WBC avg per field
WBC avg x 2,000 = WBC estimate

Question 4

Formula used for platelet estimate:

Answer 4

Total/10 = Platelet avg per field
Platelet avg x 20,000 = Platelet estimate
