Vitamin K deficiency thus activate) certain enzymes involved in coagulation: Factors II, VII, IX, X, and protein C and protein S. Inability to activate the clotting cascade via these factors leads to the bleeding symptoms mentioned above. Notably, when one examines the lab values in Vitamin K deficiency [see below] the prothrombin time is elevated, but the partial thromboplastin time is normal or only mildly prolonged. This may seem counterintuitive given that the deficiency leads to decreased activity in factors of both the intrinsic pathway (F-IX) which is monitored by PTT, as well as the extrinsic pathway (F-VII) which is monitored by PT.
Vitamin D deficiency in Australia Nowadays through technological advancements Vitamin D deficiencies are now identified and thus calculated through the measurement of the serum 25-OH. According to the Australian Bureau of Statistics National Health Measures Survey (NHMS), the recommend Vitamin D levels to determine deficiency are categorised as follows: •Adequate levels: > 50 nmol/L •Mild deficiency: 30-49 nmol/L •Moderate deficiency: 13 – 29nmol/L •Severe deficiency: < 13 nmol/L This fundamental fat-soluble vitamin has been long known for its important role in calcium absorption in the body, especially in musculoskeletal health. The health impacts commonly caused by deficiency of Vitamin D are rickets in children and
