There is some debate within our lab on how manual cell count qc should be performed. According to JACHO, qc should be performed in duplicate every 8 hrs per individual tech. The debate comes in, when the patient requires a manual diff on the cell count. Some interpret the regs as that we should perform qc on the cell count and qc of the diff portion, others interpret it as performing qc and documenting the cell count only. Wanting to know what everyone else interprets it as, and what you do in your labs. Thanks
