What we measure
This test measures levels of essential vitamins and minerals in your blood, as well as total cholesterol and C-reactive protein (CRP). All of these substances can be influenced by diet, so your results can provide helpful insight on whether your body is getting the sustenance it needs.
This test can help indicate whether you’ve got a nutritional deficiency.
Most of us have the best intentions when it comes to eating a healthy, balanced diet, but for whatever reason—responsibilities, commitments, or simply not knowing which foods we should eat—we might not quite get there.
Vitamin deficiencies common in the UK, along with other diet-related issues such as high cholesterol.
It can be difficult to realise you’ve got a deficiency based on symptoms alone. For one, some symptoms are vague and could have multiple explanations (there may be 1,001 reasons why you feel irritable, for example); for another, not all deficiencies have symptoms in the early stages.
A blood test can tell you how much of each nutrient is in your bloodstream and whether this falls within a normal range. This test can give you a thorough overview of where you’re at in terms of essential vitamins and minerals, plus other health markers related to diet.
what to expect
Your results will tell you how much of each nutrient and substance is present in your blood, and whether this is within a normal range.
Because there are recommended healthy levels for vitamins and minerals, you’ll be able to get a fairly clear overview of where you’re hitting the mark and where you might be lacking. These insights could help inform decisions for how you could live healthier, like eating more greens, for example.
However, it’s important to note that your results aren’t a diagnosis—only a doctor can diagnose you with disease or a deficiency.
Nutritional deficiencies are usually treated with dietary changes and supplements, but in some cases may be a signal that something else is going on. Speak with your doctor if you’re not sure what your results mean.

It’s generally recommended that you fast before having this test. This means that you can’t eat or drink anything except water for 8-10 hours beforehand.
Your time sleeping counts as time fasting, which is why blood tests are often scheduled in the morning.
Nope, there’s no need to stop taking your regular vitamin supplements before the test.
If you’re taking a supplement containing biotin, which is commonly found in products promoting nail, skin, and hair health, it’s recommended that you stop taking it for at least 48 hours ahead of the test.
If you’ve been prescribed biotin by your doctor, then check in with them before you stop taking it.
Other than that, there’s nothing specific you need to do.
Your test results will give you a general overview of where all your nutrient levels are at, including where you may be lacking.
You can use these insights to consider which lifestyle changes you could make to live healthier: for example, if you have a low iron reading you may choose to eat more green, leafy vegetables.
However, your results aren’t a diagnosis. To confirm whether you have a deficiency, or to check if your readings are being caused by an underlying health condition, you’ll need to check in with your doctor.
