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

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

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