Haemoglobin
The oxygen-carrying part of your red blood cells.
Why it matters
Low levels are linked to feeling tired or short of breath.
Price is for one test. No subscription.
Complete Health Profile is our widest look at your health from one appointment: 98 biomarkers from a blood and urine sample. It includes a full cholesterol profile with extended heart markers (apolipoproteins, lipoprotein(a), small dense LDL and high-sensitivity CRP), blood sugar and insulin, liver and kidney function, thyroid with antibodies, iron, vitamin D, B12 and folate, bone, pancreas, muscle, immunity and inflammation markers, H. pylori, total IgE and a urine test.
It also includes a hormone panel matched to your sex. Everyone gets testosterone, SHBG, free androgen index, oestradiol, prolactin, LH and FSH. Women also get progesterone, and men get PSA. You give your sex at checkout, so the right version (Randox Everyman or Everywoman) is run.
Booking at a UK partner clinic? Your appointment also includes body measurements: blood pressure (systolic and diastolic), pulse, height, weight, waist and hip circumference, and your waist-to-hip ratio. These are only taken at our partner clinics, not at the Chxhealth clinic in County Durham.
You get a plain-English PDF report by email showing each result against its reference range, in up to 4 working days from when your sample is taken. Samples are analysed by Randox Laboratories, accredited by UKAS to ISO 15189.
Sample: 5 blood tubes and a urine sample, taken at a clinic.
Sample requirements
Collected at either our Chxhealth clinic in Lanchester (book your appointment during checkout) or at one of our 50+ UK partnered clinics (you'll receive a separate booking email after checkout). Phlebotomy fee included in the price.

Total cholesterol includes the cholesterol carried in LDL, HDL and other particles. A high result can be linked to a greater likelihood of heart and circulation problems, but because it includes 'helpful' HDL, it is best read alongside your LDL, HDL and cholesterol ratio. A raised result is worth discussing with your GP, who will consider your overall risk.
More about Total Cholesterol
Alkaline phosphatase (ALP) comes mainly from the liver and bones. A raised level can be linked to bile duct problems such as gallstones, liver conditions, bone growth or healing after a fracture, low vitamin D and bone conditions such as Paget's disease. Doctors often look at GGT alongside it: if GGT is also raised, the liver is the more likely source. A persistently raised result is worth discussing with your GP.
More about Alkaline Phosphatase
A raised creatinine can suggest your kidneys are filtering less well. It can also be pushed up by dehydration, high muscle mass, very hard exercise, eating cooked meat before the test, creatine supplements and some medicines. A mildly raised result is often repeated, and it is worth discussing with your GP, especially if your eGFR is also low.
More about Creatinine
A low C-peptide suggests your pancreas is making little insulin of its own. This can be seen in type 1 diabetes and sometimes in long-standing type 2 diabetes. Levels are also naturally lower when blood sugar is low, so C-peptide is always read alongside your glucose result. An unexpectedly low result is worth discussing with your GP.
More about C-Peptide
Ketones are made when the body burns fat for energy instead of glucose. Finding ketones in urine is common after fasting, a low-carbohydrate diet, prolonged exercise, vomiting or not eating during illness. People with diabetes who find ketones alongside high blood sugar should discuss this with their diabetes team or GP.
More about Ketones
A low ferritin means your iron stores are running low. It is the most reliable early sign of iron deficiency and can fall before your haemoglobin drops. Common causes include heavy periods, pregnancy, a diet low in iron, blood loss from the gut and coeliac disease. It is worth discussing with your GP to find the cause, especially for men and women after the menopause.
More about Ferritin
TSH is made by the pituitary gland to tell the thyroid to produce hormones. A raised TSH usually suggests the thyroid is underactive and the pituitary is working harder to push it, which may cause tiredness, weight gain, constipation, feeling cold and low mood. It can also rise temporarily after illness. A high result is worth discussing with your GP.
More about Thyroid Stimulating Hormone
Low testosterone can be linked to low sex drive, erection problems, tiredness, low mood and loss of muscle. Causes include gradual ageing, carrying extra weight, type 2 diabetes, poor sleep, illness, alcohol, some medicines and problems with the testes or pituitary gland. UK guidance is that a low result should be confirmed with a repeat morning test before any conclusions, so it is worth discussing with your GP.
More about Testosterone
This test measures your folate status, which includes folic acid from supplements and fortified foods. A low result can be linked to anaemia with larger than normal red blood cells, causing tiredness, low energy or breathlessness. It may reflect diet, heavy alcohol use, certain medicines or problems absorbing nutrients. A low result is worth discussing with your GP.
More about Folic Acid
The most common cause of a high blood calcium is an overactive parathyroid gland. Other causes include dehydration, too much vitamin D and, less commonly, some cancers. Symptoms can include thirst, passing more urine, constipation, tiredness and confusion, though mild rises often cause none. A raised result is worth discussing with your GP.
More about Calcium
Creatine kinase is an enzyme that leaks into the blood when muscle is damaged or stressed. A raised level most often follows hard exercise, an injury, a fall or an intramuscular injection. It can also be linked to some medicines, including statins, an underactive thyroid or muscle conditions. A high result, especially with muscle pain, weakness or dark urine, is worth discussing with your GP.

Easy-to-read results sent from us to your inbox.
After you order, you will receive an email with a link to book your appointment. You can choose the Chxhealth clinic in Lanchester, County Durham, or one of our 50+ UK partner and pop-up clinics. View all clinic locations.
No. The phlebotomy fee is included in the price. There are no hidden costs at the appointment.
It isn’t required, but for tests that include glucose, lipids (cholesterol) or insulin, fasting is recommended for the best results. If you fast, drink water only. If you have diabetes or another medical condition, check with your GP before fasting. If you’d rather not fast, that’s fine: just let us know at your appointment.
Yes, keep taking your medication as normal. Some medicines can affect particular markers; for example, blood thinners such as aspirin or warfarin can affect clotting tests. If you are unsure, contact us before booking.
Samples are analysed by Randox Laboratories, a UK clinical laboratory accredited by UKAS to ISO 15189.
You will receive a plain-English PDF report by email. It shows each biomarker, your result, the reference range the laboratory uses and a short explanation of what each marker measures.
Yes. The PDF report is designed to be shared. You can email or print it for your GP or another healthcare professional.
No. Chxhealth is a biomarker and genetic data provider; we do not diagnose, treat or prescribe. Your report shows where your results sit against the reference range, and anything outside the typical range is flagged so you can follow it up with a healthcare professional.
Chxhealth complies with UK GDPR. Your personal data and results are stored in encrypted, UK-based systems and are never shared with third parties without your explicit consent. You can ask for your data to be exported or deleted at any time.
If you cancel before your sample has been taken, we offer a full refund. Once your sample has been taken and sent to the laboratory, a refund is not possible because the lab work has been done. See our refund policy for full terms.
98 for men and 98 for women. Everyone gets the same core panel, including seven hormones: testosterone, SHBG, free androgen index, oestradiol, prolactin, LH and FSH. Women also get progesterone, and men get PSA. You give your sex at checkout, so the lab runs the right version.
Yes, if you book at one of our UK partner clinics. The appointment there also includes blood pressure (systolic and diastolic), pulse, height, weight, waist and hip circumference, and your waist-to-hip ratio, and they appear in your report alongside your blood and urine results. These measurements aren't taken at the Chxhealth clinic in County Durham, so choose a partner clinic if you'd like them included.
It adds a standard cholesterol profile (total, LDL and HDL cholesterol, the cholesterol ratio and triglycerides), creatine kinase, parathyroid hormone, rheumatoid factor, the microalbumin/creatinine ratio and the FIB-4 liver score, and gives men the full hormone panel. Advanced GP3 includes a coeliac antibody test, CA-125 for women and a cardiovascular risk score, which this profile doesn't.
Yes. It measures total, LDL and HDL cholesterol, the cholesterol ratio and triglycerides, plus extended heart markers: apolipoproteins A-I, B, CII, CIII and E, the ApoB/ApoA-I ratio, lipoprotein(a), small dense LDL and high-sensitivity CRP. These can be linked to cardiovascular risk but don't measure how your heart is working.
No. It measures total IgE, a general allergy marker that can be raised in people with allergies, eczema or asthma. It doesn't show which foods, pollens or other triggers you react to; our allergy panels test specific allergens. A raised total IgE is worth discussing with your GP.
Fasting is recommended for the best results, but it isn't required. Glucose, insulin, C-peptide and triglycerides are affected by recent food, and testosterone is best measured in the morning. If you fast, drink water only, and book a morning slot if you can. Men should avoid ejaculation and vigorous cycling for 48 hours beforehand, as both can raise PSA. If you take biotin, tell us, as it can affect thyroid and hormone results. Keep taking any prescribed medication unless your doctor has told you otherwise. If you have diabetes or another medical condition, check with your GP before fasting.
You can book on any day. If you have a regular cycle, days 2 to 5 (day 1 is the first day of your period) make FSH, LH and oestradiol easiest to read. Progesterone is most useful about 7 days before your next period, so one sample can't be perfectly timed for every hormone. Note your cycle day when you book. If you use hormonal contraception or HRT, results will reflect that.
Results are delivered in up to 4 working days from when your sample is taken. You receive a plain-English PDF report by email showing each biomarker, its reference range and a short note on what it measures. Working days exclude weekends and bank holidays.
Your report flags any result outside the reference range. With this many markers, one or two results just outside range are common and often not significant. Recent illness, food, exercise and cycle day can all move results. One result on its own is not a diagnosis, and Chxhealth does not diagnose or treat, so share your report with your GP, who can decide whether to repeat the test or look further.
