What is the Vitamin K test used for?
This test is primarily used to detect vitamin K insufficiency, but it can also be used to examine and diagnose the disorders listed below:
- Liver disease
- Infant hemorrhagic disease
- Bleeding Disorders
What is included in the Vitamin K test?
It is rare to order vitamin K level tests since they are rarely available. The test is rarely used to screen for or to assist in diagnosing vitamin K deficiency since abnormal bleeding and easy bruising is usually signs of a vitamin K deficiency. A prothrombin time test is a primary test used to evaluate the bleeding (PT). If the PT results are prolonged and it is considered that this is due to a lack of vitamin K, oral supplements or injections of vitamin K are given. If the bleeding stops and the PT/INR levels return to normal, a vitamin K shortage is suspected as the culprit.
Procedure for Vitamin K test
The phlebotomist would first wrap a tourniquet around your arm, then wipe the region with antiseptic; he would then use a regular size syringe to identify the nearest vein and take the needed volume of blood into a tiny container. This sample is then analysed to establish whether or not you are deficient in vitamin K. If you are indeed deficient in vitamin K, your doctor may recommend new dietary changes and vitamin supplements oral or injectable to assist in raising vitamin K levels in your body.
How to prepare for the Vitamin K test?
In general, no extra preparation is required to complete this test; nevertheless, it is recommended that you wear short sleeves to provide your healthcare practitioner free access to your arm. The test is rather easy, and once your doctor has received his sample, he will quickly analyse the blood to determine the quantity of vitamin K in it. A vitamin K deficiency may be crippling, causing exhaustion over time. It is critical that you keep your doctor up to date on your current health issues and the drugs you are taking since this might affect the level of vitamin K in your blood.
Things to consider after the Vitamin K test is complete
Consult your doctor once the test results are available, and he or she will prescribe therapy based on the results. Please do not attempt to self-diagnose your medical problem.

What do abnormal Vitamin K test results indicate?
Severe vitamin K deficiency can result in bruising and bleeding because the blood takes longer to clot. It’s very rare for adults to have Vitamin K deficiency it’s more commonly found in babies. Because the body requires vitamin K for healthy bone, vitamin K deficiency may impair bone strength and cause osteoporosis.
The normal range for vitamin K is 0.2-3.2 ng/mL, although one source claims that levels below 0.5 ng/mL are related to poor blood coagulation. According to another source, the reference range is 0.10-2.2 ng/mL. Vitamin K is usually not tested as the deficiency is diagnosed by simply doing a blood coagulation test called Prothrombin Time (PT). If the PT is prolonged you would be diagnosed with Vitamin K deficiency.
Disclaimer: Please consult with your doctor for interpreting the test reports.
What is the Vitamin K test?
Vitamin K is essential for coagulation, often known as blood clotting. Clotting is a mechanism that aids in the prevention of excessive bleeding both within and outside the body. Vitamin K is required by your body to create the proteins involved in the clotting process. Your body does not have enough of these proteins if you are vitamin K deficient. Bleeding excessively is a symptom of vitamin K insufficiency.
Scientists also believe that vitamin K helps bones grow and stay strong, but they are still researching this. Vitamin K levels tests are not widely available and are seldom ordered. They are not commonly used to screen for or diagnose vitamin K deficiencies since a shortage of vitamin K is generally identified when there is unexpected or excessive bleeding or easy bruising.
How to read the Vitamin K test report?
A doctor will inquire about a person’s medical history to check whether they have any risk factors for vitamin K insufficiency.
A coagulation test is known as the prothrombin time, or the clinician may use PT test. They collect a small amount of blood and then add chemicals to see how long it takes to clot.
The clotting time for blood is normally 11 to 13.5 seconds. It might be due to a vitamin K shortage if it takes longer.
Before conducting this blood test, people may need to avoid meals high in vitamin K.
The normal range for vitamin K is 0.2-3.2 ng/mL, although one source claims that levels below 0.5 ng/mL are related to poor blood coagulation. According to another source, the reference range is 0.10-2.2 ng/mL.
Why book a Vitamin K test?
A prothrombin time test is a primary test used to evaluate the bleeding (PT). If the PT results are prolonged, and it is considered that this is due to a lack of vitamin K, oral supplements or injections of vitamin K are given.
Vitamin K test at home – how does it work?
The Vitamin K test is just like any other blood test. A lab technician visits your home when you book your tests through the MFine app. The lab technician first cleans the arm and then inserts a syringe into a vein. The required amount of blood is then taken into a vial. The lab technician then removes the needle and places cotton wool or a bandage over the prick.
Are there any risks involved with Vitamin K tests?
Adults are more likely to suffer from vitamin K insufficiency and the related symptoms if they:
- Use blood thinners, also known as anticoagulants, which prevent clots but decrease vitamin K activation
- Take antibiotics that inhibit vitamin K synthesis and absorption
- Don’t obtain enough vitamin K from their diets
What can affect the results of the Vitamin K test?
Many medicines can interfere with vitamin K’s effects. Antacids, blood thinners, antibiotics, aspirin, and medications for cancer, seizures, and other disorders.

The most common sign of vitamin K deficiency is bleeding (haemorrhage)—whether it be into the skin (producing bruises), from the nose, from a cut, in the stomach, or the intestine. Vomiting with blood can occur when there is bleeding in the stomach. Urine or faeces may include blood, or the stools may be tarry black.
What drugs are affected by vitamin K?
Several drugs and foods, like, blood thinners, phenytoin, some antibiotics, orlistat (a weight-loss treatment), and bile acid sequestrants, interact negatively with vitamin K. Generally, you get your daily vitamin K requirements from the foods you eat.
What are the typical amounts of vitamin K?
Vitamin K is a lipid-soluble vitamin that is needed for the formation of coagulation proteins. The normal range for vitamin K is 0.2-3.2 ng/mL, although one source claims that levels below 0.5 ng/mL are related to poor blood coagulation. According to another source, the reference range is 0.10-2.2 ng/mL.
What is the purpose of a vitamin K blood test?
Vitamin K levels tests are not widely available and are seldom ordered. They are not often used to screen for or assist in the diagnosis of vitamin K deficits since a shortage of vitamin K is usually identified when there is unexpected or excessive bleeding or easy bruising.
Who is most vulnerable to vitamin K deficiency?
Most newborns, regardless of gender, colour, or ethnicity, are at a higher risk for VKDB until they begin eating regular meals, generally around the age of 4-6 months, and until the normal gut flora begins producing vitamin K.
There are various reasons why newborns are especially vulnerable to vitamin K deficiency:
- Breast milk is deficient in vitamin K.
- Vitamin K does not pass properly from the placenta to the infant.
- A newborn’s liver is unable to absorb vitamin K efficiently.
- A newborn’s gut cannot make vitamin K2 during the first few days of life.
