Measures vitamin K1 and K2 status, markers involved in blood clotting and calcium regulation for bone health. A specialist single-marker test for anyone with a specific reason to check vitamin K levels.
1 biomarker as listed by Medichecks.
Vitamin K supports normal blood clotting, helps regulate calcium levels in the blood and plays a part in healthy bone metabolism. This test measures both K1 and K2, but as a single combined marker it is a narrow, specific check rather than a broad nutritional screen.
This is one of the more restrictive tests in our data: your sample has to be collected in person at Medichecks' Inuvi Clinic in London, because it is not suitable for posting, and there is no home nurse or at-home option. That is reflected in a low collection convenience score, and the price, at £149, is around 75% above the £85 median for similarly sized vitamin tests we track, which pulls down the value-for-money score too.
Clarity and trust scores are both strong, since Medichecks publishes the biomarker, sample type and turnaround in full, and every result comes with a doctor's written comment, backed by the company's Trustpilot rating and lab accreditation. If you need this specific marker, those factors are reassuring, but the combination of price and a single collection location is a real practical constraint.
This suits someone in or near London who has a specific reason to check vitamin K1 and K2, for example concerns about clotting or bone metabolism raised by a GP. If travelling to a clinic in London is not practical for you, or £149 for a single combined marker is more than you want to spend, discuss with your GP whether this test is the right next step or whether a different route to testing this marker would suit you better.
This is a blood test that must be taken in person at Medichecks' Inuvi Clinic in London, as the sample is not suitable for posting; there is no home nurse visit or at-home kit for this test. Once your sample reaches the lab, results are typically ready in around 9 days, and a doctor reviews and comments on your result as standard.
