Hello and welcome to HCM,
All blood parameters -
hemoglobin,
hematocrit, MCV and
RBC count are all within normal limits.
The total leukocyte count and differential
leukocytes are also within normal limits.
The decrease in level of MCH and MCHC are not explainable as the hemoglobin hematocrit and red cell counts are all within normal limits.
This decrease could be due to instrumental error.
However, there is nothing to worry.
Small errors can occur due to a small change in the calibration of the machine.
If you are very much concerned and worried, you can get the tests repeated.
The differential count shows slight increase in lymphocytes.
The range which is given by a particular laboratory is based on values obtained in majority of patients.
A small variation can be expected and it is normal.
There is no major change in the differential counts and thus, it does not indicate any disease process.
Thanks and take care
Dr Shailja P Wahal
