I just had a blood test and my monocyte count came back at 1.7.  The high end of the normal range was .08.  My count seems not only high, but extremely high, as it is more than double the high end of the normal range.  The rest of my blood test came back normal, and negative for mono, but Im still waiting for the results of a throat swab that will indicate whether I have strep throat.  My question is
Hello and welcome to Chat Doctor, High monocyte count occurs in cases of chronic infections like malaria, gala agar, and neoplasms. Throat infection with streptococcus bacteria will lead to increased number of neutrophils in blood and not monocytes. There is some other cause for elevated monocytes in blood. Thus, investigations are required to know the cause of elevated monocyte counts. Thanks and take care Chat Doctor.
