Hematocrit is a measure of the percentage of red blood cells in the blood. Low hematocrit levels (anemia) can cause fatigue, shortness of breath, and other symptoms.

iollo markers that associate with Hematocrit


Alanine is involved in the synthesis of heme, a key component of hemoglobin in red blood cells. Changes in alanine levels may therefore correlate with hematocrit, a measure of red blood cell volume.


Glycine is another amino acid involved in heme biosynthesis. Alterations in glycine availability could potentially impact hemoglobin production and thus hematocrit levels.
