Private blood test vs NHS: which should you choose?

NHS blood tests are free when your GP or hospital team asks for them. A private blood test lets you choose your own tests, book when it suits you and get results in days. Here’s how they compare.

When the NHS is the right choice

If you’re unwell, have new or worrying symptoms, or need tests to diagnose or monitor a condition, start with your GP. NHS tests are free when they’re clinically needed, and your GP can examine you and arrange treatment.

Why people choose a private test

You might want a test your GP doesn’t routinely offer, such as AMH, a full thyroid profile with free T3, lipoprotein(a) or a Well Person check without symptoms. Or you might simply want a convenient appointment and fast results without waiting for a GP appointment first.

Do I need a referral?

No. You can book any of our tests yourself, online or by phone.

Sharing results with your GP

Your report is yours to keep and share. Your GP may repeat a test before acting on it, which is normal practice.

What it costs

Our tests start at £55, and the price shown includes taking your blood sample and your report. See our full price list.
