A single drop of blood contains millions of erythrocytes and just thousands of leukocytes. Specifically, males have about 5.4 million erythrocytes per microliter (µL) of blood, and females have approximately 4.8 million per µL. In fact, erythrocytes are estimated to make up about 25 percent of the total cells in the body.

However, sensitivity issues and variations in laboratory methods complicate prevalence comparisons. Riboflavin status is further explored through urinary excretion metrics, with different assays showing discrepancies.

While useful for non-fasting individuals, variability and measurement challenges are present. Whole blood levels are also not commonly used for deficiency evaluation, with concentrations below 17 µmol/L indicating deficiency and above 28 µmol/L being acceptable.
