Question: High metamyelocytes (absolute) on lab results.

 leon718 - Fri May 29, 2009 4:45 pm

Hello everyone. We recently took our 5 year old son for a blood test and just received the results back. Everything seems to be normal but the pediatrician recalled our son for a repeat of the blood test for the following reason:


Everything else in the lab report seems to be within normal ranges. The only other thing that I could point out (but the doctor didn't) was the MATURE LYMPHOCYTES: 70 (REFERENCE RANGE: 25-65 %).

We are bringing him in next week for a repeat blood test, but I am going absolutely crazy right now trying not to think of the worst.

What can explain such elevated absolute metamyelocytes? What are the possible causes? Please help!

P.S. He seems to be feeling fine, with no complaints of any kind.

User avatar Hello,I would be interested to know the result of the repeat blood test.Metamyelocytes are generally not seen in peripheral blood.In these cases a bonemarrow examination may be required.These are immature cells found in the bonemarrow.There is a condition called pelger-Huet anomaly,a genetic anomaly which can cause dificulty in mistaking neurophilic band forms in people with otherwise normal results.Do check up for this.Hereditary forms of PHA are benign.Ok?
