A single finger-prick blood test that measures your calcium level, useful if you have symptoms of high or low calcium or want a quick check on your dietary intake.
1 biomarker as listed by Better2Know.
Calcium is the only marker in this kit. Your body needs it for healthy bones, muscle function and nerve signalling, and levels that run persistently high or low can point to problems with your parathyroid glands, kidneys, vitamin D status or diet. This test gives you a single reading rather than a wider metabolic picture, so it suits people who already have a specific reason to check calcium rather than those wanting a broad health screen.
Within Better2Know's own range, this is the cheaper of two ways to get the same calcium marker. The clinic-based Calcium Test costs £135 for a venous blood draw, whereas this kit costs £40 and uses an at-home finger-prick sample you post back yourself. Both report results the next working day, so the price difference is really about how the blood is collected rather than what you learn from it.
The test scores well for price and for collection convenience, since a home finger-prick sample sent by post is about as easy as testing gets, and £40 is well below the typical price of the vitamins and minerals tests we track. It loses marks on clinical depth, because a single marker only tells you about calcium and nothing else, and on results and follow-up, since Better2Know does not review your result with a doctor as standard, though it can arrange a doctor's consultation if your reading comes back abnormal. Better2Know is CQC registered and holds a Trustpilot score of 4.2 from 775 reviews, having traded since 2008.
This kit suits you if you have symptoms that could point to a calcium imbalance, such as muscle cramps, tingling in your fingers or unexplained fatigue, or if you simply want a quick check on your dietary calcium intake without visiting a clinic. Because it only measures calcium, it is not a substitute for a broader panel if you want to understand your overall bone or metabolic health.
If you would rather have blood taken by a clinician than do a finger-prick yourself, Better2Know's own Calcium Test offers the identical marker through a venous draw at a clinic, for £135. Either way, if your result comes back abnormal you should see a GP to discuss what it means and what, if anything, to do next.
You collect a small blood sample yourself with a finger-prick and post it to Better2Know's laboratory using the kit provided; a clinic-based venous draw is also available for £135. Once your sample arrives at the lab it is tested for calcium, with results typically available the next working day, viewable through Better2Know's secure online patient area. Better2Know does not review results with a doctor as standard, though it says it can arrange a doctor's consultation if your reading is abnormal.
This finger-prick kit checks your calcium level from a home sample, with results back the next working day. At £40 it costs far less than Better2Know's own clinic-based Calcium Test, which uses the same single marker and a venous blood draw. The main gap is that results are not reviewed by a doctor as standard, so you are reading a single number without clinical context.
