Some supplements may interfere with test results

THERE is a misconception that if you buy supplements and herbal remedies from the health store that they’re perfectly safe for anyone to take. And of course they are if they’re safely used. Just because they’re natural doesn’t mean they’re safe for everyone to take.

For example, grapefruit could interfere with high blood pressure medication; Evening Primrose Oil shouldn’t be taken if you have epilepsy, and you shouldn’t take turmeric or Omega 3 fish oils if you’re on blood thinners. You should always tell us if you’re on any medication or have a medical condition so that we can safely advise.

So this is why I want to tell you that the Health Products Regulatory Authority have recently advised us that you should tell your doctor if you’re taking biotin supplements before having any blood tests.

You don’t have to worry about this unless you are planning on having blood tests. Biotin may interfere with the results, but it is otherwise considered safe. So if you’re planning on having blood tests take a look at your medication and supplements and let your doctor know if they contain biotin. They will advise the laboratory. These tests could include tests for cardiac markers, hormones, tumour markers, and infection markers. The last thing you want is incorrect test results.

For example, false test results could show a low result for troponin which may lead to a missed diagnosis of heart attack. Or some test results can mimic hyperthyroidism meaning that you could be prescribed medication that you don’t need to be taking.

Biotin is a vitamin that you may be familiar with; it’s one that I have spoken about many times. It’s a popular B vitamin that helps to improve hair growth, reduce hair loss, and improve nail growth. Biotin is found in a variety of different supplement blends including ones for skin and nail health, B complex formulas, multivitamins, prenatal formulas, and is also in some medications. It will be listed in the ingredients list. Biotin is also known as vitamin B7, vitamin H, or co-enzyme R.

So if you’re due to have a blood test and you take a supplement or medication that contains biotin make sure to inform your doctor first.
