| Additional information | Manual methods are much less accurate, and give somewhat lower results (reference range: 20-89 x109/L). A manual assay will be performed if required due to sample or fluorescent assay problems. The manual assay requires a separately ordered and charged RBC count, if one is not available, to calculate the result. |
