A clear read on your calcium regulation
Parathyroid hormone is made by four small glands in your neck and it controls how much calcium sits in your blood, bones and kidneys. Measuring it helps diagnose hyperparathyroidism (too much PTH) and hypoparathyroidism (too little), and makes sense of a high calcium result, unexplained bone or kidney stone symptoms, or a wider bone-health picture.
Follow up on high calcium
If a recent blood test showed raised calcium, checking PTH is the standard next step to work out why.
A clear, simple result
Your report shows your PTH level against the standard reference range, in plain English, with any next steps.

A PTH test can be a helpful step in a few different situations.
Good to know: PTH is most useful when read alongside a recent calcium result. If you do not have one, mention it when you book and we can advise on the right combination for your situation. If your questions also involve thyroid function, see our thyroid health blood test.

Difficult veins? We find them with ultrasound
If you have fragile or hard-to-find veins and have had failed attempts before, our consultant radiologists can take the sample under real-time ultrasound. It is the only such service in South Wales, and patients travel to us from across Wales and the West for it.
Nobody had managed to take my blood in years without several attempts. Here it was done first time with the ultrasound. Such a relief.

Common questions about the PTH test
How much is the parathyroid hormone blood test?
£131 all inclusive. That covers the blood draw, the PTH measurement, and a plain-English report emailed to you. A £50 deposit secures your appointment and comes off the total.
What does PTH tell me?
Parathyroid hormone is the main hormone that controls calcium levels in your blood, bones and kidneys. Measuring it helps diagnose hyperparathyroidism (an overactive parathyroid, often causing raised calcium) and hypoparathyroidism (an underactive parathyroid), and supports workups for kidney stones and bone health. Your report shows whether your PTH sits within the standard reference range and flags anything unusual.
Do I need to have my calcium tested too?
PTH is at its most useful when read alongside a recent calcium result (and sometimes vitamin D). If you already have one from your GP or a previous test, bring it. If you do not, please mention it when you book so we can advise on the right combination for your situation.
Do I need to fast or time the test?
No fasting is required. PTH does vary a little through the day, so a morning appointment is often preferred where possible. We will confirm anything specific to your appointment when you book.
Do I need a GP referral?
No. This is a self-refer test. Book online or call 029 2199 9300.
How quickly will I get my result?
Your report is emailed to you once the laboratory has processed the sample. Ask us when you book and we will give you a clearer idea of timing.
Where is the blood taken?
At our Penarth clinic (13 Washington Buildings, CF64 2AD) or our Cowbridge clinic (10 High Street, CF71 7AG). Both are a short drive from Cardiff with easy parking.
I have difficult veins. Can you still take blood?
Yes. Our consultant radiologists can take the sample under real-time ultrasound, the only such service in South Wales. Mention it when you book so we can allow time.
Can a doctor talk me through my result?
Yes. You can book a private GP appointment and one of our doctors will go through your result and next steps.
Want a doctor to explain the result?

Important: The PTH test measures your parathyroid hormone level against a standard reference range. It is most useful when interpreted alongside a recent calcium result, and often with vitamin D and phosphate, by a clinician who knows your history. A single number does not diagnose a parathyroid or bone condition on its own. We recommend discussing your result with your own GP, or booking a private GP appointment with us, before making decisions based on it. Lab values alone do not constitute medical advice.
