Vitamin K deficiency is typically measured by assessing levels of prothrombin time (PT) and activated partial thromboplastin time (aPTT) in the blood. Additionally, measurement of vitamin K-dependent clotting factors, such as Factor II, VII, IX, and X, can also be used to diagnose deficiency. Specialized tests to directly measure vitamin K levels in the blood can also be performed.
Low vitamin C levels can indicate a deficiency in this essential vitamin, which is important for immune function, collagen production, and wound healing. Symptoms of low vitamin C levels can include fatigue, susceptibility to infections, and slow wound healing. It is important to consume an adequate amount of vitamin C through diet or supplements to maintain optimal health.
