Antiparietal Cell Antibody
This test detects antibodies against cells in the stomach lining that produce intrinsic factor, needed to absorb vitamin B12. It helps diagnose autoimmune gastritis and pernicious anemia, which can cause fatigue, neurological symptoms, and poor energy metabolism.
Not especially athlete-specific. However, B12 deficiency impairs oxygen transport and energy production, potentially affecting endurance and recovery. Athletes with persistent fatigue, especially vegetarians or those with GI issues, may warrant screening if other causes are ruled out.
