Coagulopathy is a blood disorder that prevents proper clotting, leading to excessive bleeding or abnormal clot formation. It is caused by deficiencies in clotting factors, often due to vitamin K deficiency, liver disease, or genetic disorders affecting coagulation proteins. The Vitamin K test is the most important test for diagnosing nutritional causes of coagulopathy.

Coagulopathy is caused by deficiencies or dysfunction in blood clotting factors that prevent proper coagulation. Vitamin K deficiency is a common cause because this vitamin is essential for producing clotting factors II, VII, IX, and X in the liver. Other causes include liver disease that impairs clotting factor production, genetic disorders like hemophilia, anticoagulant medications such as warfarin, and conditions that affect vitamin K absorption like celiac disease or inflammatory bowel disease.
The Vitamin K test is the most important test for coagulopathy because it identifies one of the most treatable underlying causes of clotting disorders. Vitamin K deficiency directly impacts the liver's ability to produce factors II, VII, IX, and X, which are essential for normal blood clotting. This test measures your vitamin K levels to determine if deficiency is contributing to prolonged bleeding times or excessive bleeding. When combined with standard coagulation tests like PT/INR and PTT, vitamin K testing provides a complete picture of your clotting function and helps guide targeted treatment.
You should get tested if you experience easy bruising, frequent nosebleeds, bleeding gums, unusually heavy menstrual periods, or prolonged bleeding from minor cuts. Testing is also important if you notice blood in your urine or stool, experience unexplained bleeding, or are taking blood thinners like warfarin. People with liver disease, malabsorption conditions, or those on long-term antibiotics should also consider testing since these factors increase the risk of vitamin K deficiency and coagulopathy.

What this means
Your vitamin K level is slightly below the optimal range, which may affect blood clotting efficiency and bone health over time. While this is not an emergency, maintaining adequate vitamin K is important for preventing easy bruising and supporting strong bones as you age.
Recommended actions
Increase intake of leafy greens like kale, spinach, and collard greens daily
Include vitamin K2-rich fermented foods like natto, sauerkraut, or aged cheeses
Eat vitamin K-rich foods with healthy fats (olive oil, avocado) for better absorption
Consider retesting in 2-3 months after dietary improvements
