Urine Leukocytes are white blood cells that can be detected in the urine. The presence of leukocytes in the urine may indicate a urinary tract infection or other inflammatory condition.
Alanine is an amino acid that can be metabolized by leukocytes as an energy source to support immune cell function and proliferation. Elevated alanine levels may reflect increased leukocyte activity.

Glutamine is a key fuel source for leukocytes and is important for leukocyte proliferation and function. Low glutamine levels can impair immune response.

Lactic acid is produced by leukocytes during inflammation and infection. Elevated lactic acid may indicate increased leukocyte activity and anaerobic metabolism.
