This is a single-marker test measuring Vitamin K1. Vitamin K1 plays a crucial role in blood clotting and bone metabolism. Assessing Vitamin K1 levels can help identify deficiencies that may be associated with conditions such as obstructive liver disease, malabsorption disorders, pancreatitis, prolonged diarrhea, or antibiotic overuse. Identifying and addressing deficiencies is essential for managing blood clotting disorders, supporting bone health, and preventing hemorrhagic conditions, particularly in newborns.
