Many men only get a blood test after something's already gone wrong — a health scare, a partner's insistence, or a routine check that turns up an abnormal result. Low energy, weight gain around the middle, poor concentration, low mood or a falling sex drive are easy to write off as ‘just getting older’ or work stress. Often they're not one thing at all, but a combination of hormonal, metabolic and organ-system changes that only show up clearly when you test everything together. The Advanced GP3 (Male) blood test screens 59 markers in one sitting — including testosterone, prostate health, cardiovascular risk and thyroid function — so instead of guessing, you get a full, clinician-reviewed picture.
What's actually behind ‘just feeling off’
When men come to us with fatigue, low libido, weight gain or poor concentration, a handful of underlying issues come up again and again:
- Low testosterone — falls gradually with age but can also drop due to stress, poor sleep, excess weight or underlying illness, affecting energy, mood, muscle mass and libido.
- Thyroid dysfunction — less commonly discussed in men, but an underactive thyroid causes the same fatigue and weight gain it does in women.
- Rising cardiovascular risk — cholesterol, blood pressure and blood sugar often drift upward silently through your 30s and 40s with no symptoms at all.
- Iron imbalance — less commonly checked in men, but relevant with certain diets, alcohol intake or unexplained fatigue.
- Prostate changes — urinary symptoms, or simply reaching the age where a baseline PSA is a sensible thing to have on record.
- Liver strain — from alcohol, medication or weight gain, usually silent until picked up on routine bloods.
When to seek help
Most of these causes are common, gradual and very manageable once identified — this is a screening test, not an emergency assessment. But new chest pain, breathlessness, coughing blood, testicular lumps, or blood in your urine warrant urgent same-day assessment rather than a routine blood test.
As a rule, seek urgent care for severe, sudden or rapidly worsening symptoms, and book a routine test for milder, longer-standing concerns like the ones above.
What the Advanced GP3 (Male) checks
Rather than testing one thing at a time, the Advanced GP3 (Male) panel screens 59 markers across 14 areas of your health in a single blood draw. Here's what each group can tell you:
Hormones
This panel checks testosterone, SHBG and free androgen index. These hormones influence energy, mood, libido, weight and cycle regularity, and imbalances are common at various life stages.
Prostate health
This panel checks PSA (prostate specific antigen), a standard screening marker for prostate health — relevant for men particularly from their 40s and 50s onward, or with urinary symptoms or a family history of prostate problems.
Thyroid
This panel checks TSH, free T4, free T3 and thyroid antibodies. An underactive or overactive thyroid can cause tiredness, weight changes, low mood, hair thinning or a fast or irregular heartbeat — often mistaken for stress or "just getting older" — so a clinician can spot dysfunction even before it's obvious from symptoms alone.
Heart & cholesterol
This panel checks your full lipid profile plus apolipoprotein B and lipoprotein(a) — advanced markers that refine cardiovascular risk beyond standard cholesterol, building an accurate cardiovascular risk picture. Cholesterol and related lipid markers are among the strongest predictors of long-term heart and stroke risk, and rarely cause symptoms until a problem is advanced.
Blood sugar
This panel checks glucose, HbA1c, insulin, creatine kinase and adiponectin, screening for diabetes and pre-diabetes, which can develop silently for years with no obvious symptoms.
Liver function
This panel checks ALT, AST, GGT, ALP, bilirubin and albumin. Liver enzymes can flag early strain from alcohol, medication, weight gain or fatty liver disease long before any symptoms appear.
Kidney function & salts
This panel checks creatinine, eGFR, cystatin C, sodium, potassium, urea and uric acid. Kidney function can decline silently for years before it's noticed, so these markers give an early warning of reduced kidney function, dehydration or salt imbalances.
Iron status
This panel checks ferritin, serum iron, TIBC, transferrin and transferrin saturation. Low iron is one of the most common, treatable causes of fatigue, breathlessness and poor concentration, often well before a full anaemia develops — a complete iron picture is far more useful than a ferritin test alone.
Vitamins
This panel checks vitamin D, vitamin B12, folate and magnesium. Deficiencies here are widespread in the UK and are linked to fatigue, low mood, muscle aches and poor immunity — and are simple to correct once identified.
Bone & mineral health
This panel checks calcium, phosphate and parathyroid hormone (PTH), giving an early picture of bone and mineral health that can also flag problems affecting energy and muscle function.
Full blood count
This panel includes a full blood count — red cells, white cells, platelets and related indices — one of the single most useful all-round checks available, screening for anaemia, infection and abnormalities in your blood.
Inflammation
This panel checks C-reactive protein (CRP), a general marker of inflammation in the body that can point towards infection, a chronic inflammatory condition, or increased cardiovascular risk.
Autoimmune screen
This panel checks rheumatoid factor, a general screening marker for autoimmune joint disease — useful context if you have unexplained joint pain, swelling or stiffness.
Pancreas
This panel checks lipase, a marker of pancreatic function assessed as part of a wider picture when abdominal symptoms or metabolic risk factors are present.

Why the Advanced GP3 (Male) is the right test
The Advanced GP3 (Male) panel is our most comprehensive male screen because the issues above rarely travel alone — a borderline testosterone result means something different next to a normal thyroid and healthy cholesterol than it does alongside early metabolic changes. Compared with the Advanced GP2 (Male), GP3 adds parathyroid hormone, cystatin C and uric acid, apolipoprotein B and lipoprotein(a) for a sharper cardiovascular risk picture, and a fuller vitamin panel — 59 markers in total.
Every result, including PSA and testosterone, is reviewed by a clinician who explains what it means for you specifically and recommends sensible next steps — which might be reassurance, a lifestyle change, or onward referral.
Frequently Asked Questions
Does this test check testosterone properly?
Yes — it includes testosterone, SHBG and free androgen index, which together give a clearer picture of your available (bioavailable) testosterone than a total testosterone result alone.
Is PSA included, and is it accurate straight after exercise?
Yes, PSA (prostate specific antigen) is included. Vigorous exercise, cycling or ejaculation in the 48 hours beforehand can temporarily raise PSA, so where possible avoid these before your appointment for the most accurate result.
Do I need to fast before this blood test?
Yes — because this panel includes glucose and HbA1c, we recommend avoiding food for around 8-10 hours beforehand (water is fine). Our team will confirm exact preparation when you book.
Do I need a GP referral to book this test?
No referral is needed. You can book directly online or by calling 0121 387 3727. Same-week appointments are available 7 days a week, 8am to 8pm.
Can I claim this on private health insurance?
Self-funded blood tests are usually paid for directly rather than through insurance, as most insurers require a referral first. If you would like to use insurance, call us on 0121 387 3727 and our team will advise on the best route for your policy.
