Men's Health Blood Tests Guide: Testosterone & PSA

Quick answer

Men's health testing centres on prostate (PSA) and testosterone checks, alongside standard cardiovascular and metabolic screening that shifts with age. The core takeaway: PSA needs shared decision-making since it is not cancer-specific, low testosterone symptoms overlap with many other causes, and lifestyle factors like weight, sleep and alcohol move most men's results substantially.

Men’s health blood tests at a glance

Men are less likely to attend health checks, yet regular testing detects the silent conditions that affect men disproportionately. This table compiles the key tests; the schedule section shows when each is usually done.

Test	Target / normal	What it detects
Total testosterone	300–1,000 ng/dL (morning sample)	Low T: fatigue, low libido, muscle loss
PSA	<4.0 ng/mL (age-adjusted)	Prostate cancer risk; prostate enlargement
Fasting lipid profile (LDL)	LDL <100 mg/dL	Heart disease risk, the leading cause of male death
Fasting glucose / HbA1c	Glucose <100 mg/dL; HbA1c <5.7%	Diabetes; type 2 is about 50% more common in men
CBC (haemoglobin)	13.5–17.5 g/dL	Anaemia; polycythaemia
Creatinine / eGFR	eGFR >60	Kidney health
LFT (ALT, GGT)	ALT <56 U/L; GGT <48 U/L	Fatty liver; alcohol-related liver damage (GGT is very sensitive)
Uric acid	3.5–7.2 mg/dL	Gout risk

Key points

PSA rises with cancer, but also with BPH and prostatitis: it is not cancer-specific.
PSA screening needs shared decision-making about benefits and harms.
Low testosterone is underdiagnosed (2 to 6 percent of men 40 to 79); symptoms overlap many other causes.
Weight, sleep and alcohol move most men's results substantially.

PSA screening: what men need to know

PSA (prostate-specific antigen) is a protein produced by prostate cells. Elevated PSA can indicate: prostate cancer (the most common cancer diagnosed in men, excluding skin cancers)¹, benign prostatic hyperplasia (BPH, non-cancerous enlargement), prostatitis (infection or inflammation). PSA is not a perfect test. It can be elevated without cancer and normal with cancer. Current guidelines vary: the American Cancer Society recommends discussing PSA screening with men from age 50 (45 if high risk, Black men or family history; 40 if very high risk). A rising PSA over time (PSA velocity) is more informative than a single value.

PSA (ng/mL)	Interpretation
<4.0	Generally reassuring; age-adjusted thresholds vary
4.0–10.0	Borderline; 25% have prostate cancer on biopsy
>10.0	High; 50%+ have prostate cancer; biopsy recommended

Testosterone deficiency (Low T): recognition and testing

Low testosterone (hypogonadism) is significantly underdiagnosed. It affects approximately 2–6% of men aged 40–79. Symptoms, fatigue, reduced libido, erectile dysfunction, low mood, muscle loss, belly fat gain, are non-specific and often attributed to ageing or stress. Always test morning testosterone (7 – 10am) as levels are 30–40% higher in the morning. If low, confirm with a repeat test and add LH/FSH to determine whether the problem is the testes (primary) or pituitary (secondary).

Recommended blood test schedule for men

Age-based screening schedule for men

From age 20: Fasting lipid profile every 5 years; blood pressure check
From age 35: Fasting glucose; lipid profile every 5 years
From age 40: Testosterone (if symptoms); fasting insulin; LFT
From age 45: Discuss PSA screening with your doctor; annual HbA1c if overweight
From age 50: PSA; colonoscopy for colorectal cancer screening; annual metabolic panel
All ages: CBC, creatinine, uric acid as indicated by symptoms

Lifestyle factors that most impact men's blood results

Visceral (belly) fat: raises triglycerides, lowers HDL, raises fasting glucose and insulin resistance, and suppresses testosterone
Alcohol: raises GGT, triglycerides and uric acid; damages liver
Smoking: accelerates atherosclerosis; doubles heart attack risk
Sleep apnoea (affects 40% of obese men): lowers testosterone, raises blood pressure and blood sugar
Physical inactivity: major driver of metabolic syndrome, insulin resistance and low testosterone

Questions to ask your doctor

Is my testosterone level low?
Should I have a PSA test?
What is my cardiovascular risk score?
Is my GGT elevated due to alcohol or fatty liver?
Should I have a colonoscopy?

Prostate health, PSA testing and what it means

Prostate-specific antigen (PSA) is a protein produced by the prostate gland that leaks into the bloodstream in greater quantities when the prostate is enlarged, inflamed, or cancerous. PSA testing is the most commonly used prostate cancer screening tool, but its interpretation is nuanced:²

PSA is age-dependent: a PSA of 2 ng/mL in a 50-year-old man is more concerning than the same value in a 70-year-old. Age-specific thresholds used in practice: under 50: above 2.5 ng/mL warrants urological referral; 50–69: above 3.0 ng/mL; 70+: above 4.0 ng/mL. However, PSA is not prostate-cancer-specific, it rises with benign prostatic hyperplasia (BPH), prostatitis, UTI, urinary catheterisation, ejaculation (PSA transiently rises by 0.5 ng/mL for 48 hours), vigorous exercise, and cystoscopy. PSA should not be measured after any of these activities.

PSA velocity (rate of rise) and PSA density (PSA divided by prostate volume on ultrasound) improve its predictive value. A PSA rising by more than 0.75 ng/mL per year is a stronger cancer signal than a single elevated result. The NHS currently runs an "Informed Choice" programme offering PSA testing on request to men over 50 who are counselled about its benefits and limitations, unlike structured screening, there is no national PSA screening programme in England.

Testosterone, the male hormonal screen

Testosterone deficiency (male hypogonadism) causes fatigue, low libido, erectile dysfunction, depression, reduced muscle mass, increased body fat, and osteoporosis. It is significantly under-diagnosed.³ Key blood tests:

Total testosterone: Should be measured between 7 and 11 am (levels peak in the early morning). A fasting sample is preferred. Below 8–12 nmol/L (laboratory-dependent) is hypogonadal; borderline values (8–15 nmol/L) require repeat measurement with SHBG for free testosterone calculation.
SHBG (sex hormone binding globulin): Binds testosterone, only "free" testosterone is biologically active. High SHBG (common in older men, liver disease, hyperthyroidism) can give a normal total testosterone with a low free testosterone (symptomatic hypogonadism). Low SHBG (obesity, hypothyroidism, metabolic syndrome) can give low total testosterone but normal free testosterone.
LH and FSH: Distinguish primary hypogonadism (testes failing, LH/FSH raised as pituitary tries to compensate) from secondary hypogonadism (pituitary/hypothalamus failing, LH/FSH inappropriately low). Secondary hypogonadism warrants MRI pituitary to exclude prolactinoma or other pituitary tumour.
Prolactin: Hyperprolactinaemia suppresses GnRH, causing secondary hypogonadism. A prolactinoma (pituitary tumour) causes LH/FSH and testosterone suppression, often with galactorrhoea, treated with dopamine agonists (cabergoline), not testosterone replacement.

Men’s health testing myths vs facts

MYTH A raised PSA means prostate cancer.

Fact: PSA is a prostate test, not a cancer test. Benign enlargement (BPH) and prostatitis raise it too, and it is not cancer-specific. PSA screening needs a shared decision-making conversation about benefits and harms before the blood is drawn.

MYTH Low testosterone is just ageing, so testing is pointless.

Fact: Low T is genuinely underdiagnosed, affecting an estimated 2–6% of men aged 40–79. Fatigue, low libido and muscle loss overlap many other causes, which is exactly why a morning testosterone measurement matters rather than guesswork.

MYTH If you feel fine, you don’t need blood tests.

Fact: Hypertension, diabetes, high cholesterol and prostate problems are all silent in their early stages. The tests above exist precisely to catch what feeling fine can hide.

MYTH Lifestyle doesn’t move blood results much.

Fact: Belly fat, alcohol, smoking, sleep apnoea and inactivity move most men’s results substantially — triglycerides, HDL, glucose, testosterone and GGT all respond to lifestyle. That is also why they respond when habits change.

What matters most in men’s health testing

Decide about PSA before the draw, not after. The benefits-and-harms conversation belongs up front; a surprised abnormal PSA helps nobody.
Time testosterone correctly. Always an early-morning sample (7–11am); afternoon values under-read and confuse the picture.
Follow the age schedule. Lipids from 20, glucose from 35, PSA discussion from 45, colonoscopy from 50 — the table above shows the rhythm.
Fix the movers first. Weight, sleep, alcohol and smoking shift most results; addressing them improves both the numbers and the underlying risk.

Practical notes

For PSA testing, avoid ejaculation for 48 hours beforehand, and tell the doctor about recent urinary infections, prostate exams, or long-distance cycling — all can raise PSA. For testosterone, morning fasting draws are standard because levels peak early in the day.

Bring your medicine list — especially finasteride or dutasteride, testosterone or ‘T-booster’ supplements, and biotin — along with notes on symptoms such as urinary changes, fatigue, or libido, and your family history of prostate disease.

Read PSA and testosterone in context: age, symptoms, and trends all count. A single PSA value or a single low morning testosterone rarely settles anything alone — ask your doctor what the result means for you and what confirmatory step, if any, is planned.

For follow-up, ask when to repeat each test, whether the same lab and the same conditions matter for comparability, and which symptoms should prompt an earlier return than scheduled.

In India

A PSA test is typically ₹500–₹1,200; a male hormone panel including testosterone is typically ₹1,500–₹4,000, though prices vary by city and lab. Confirm the panel's exact contents before paying.

Choose NABL-accredited labs, and for testosterone confirm that home collection — available in major cities — is scheduled in the morning, when levels are highest. The reference range printed on your own report is the one that counts, since methods and ranges differ between labs.

Frequently Asked Questions

What should men know about PSA screening?

PSA is a protein produced by prostate cells, and it rises with prostate cancer — but also with benign enlargement (BPH) and prostatitis. It is not cancer-specific. Age-adjusted thresholds are used in practice (for example, above 3.0 ng/mL at ages 50–69 warrants urological discussion), and PSA velocity and density improve its meaning. Screening should follow a shared decision-making conversation about benefits and harms.

How is testosterone deficiency recognised and tested?

Low testosterone (hypogonadism) is significantly underdiagnosed, affecting roughly 2–6% of men aged 40–79. Symptoms — fatigue, reduced libido, erectile dysfunction, low mood, muscle loss, belly fat gain — are non-specific and often blamed on ageing. Always test with a morning sample (levels peak 7–11am); LH, FSH, SHBG and prolactin help distinguish primary from secondary causes.

How does age change PSA interpretation?

PSA is age-dependent: 2 ng/mL in a 50-year-old is more concerning than the same value in a 70-year-old. Practical thresholds are roughly above 2.5 ng/mL under 50, above 3.0 at 50–69, and above 4.0 at 70 and over. A rise of more than 0.75 ng/mL per year is a stronger cancer signal than one elevated reading.

What blood tests does the male hormonal screen include?

Total testosterone (morning, fasting preferred), free testosterone, SHBG (only free testosterone is biologically active, and high SHBG can hide a low free level behind a normal total), LH and FSH to separate primary from secondary hypogonadism, and prolactin, since raised prolactin suppresses the whole axis.

My PSA is a little above the range — does that mean cancer?

No — PSA rises for many benign reasons: age, prostate enlargement, infection, recent ejaculation, or even a long bike ride. An elevated PSA is a prompt for your doctor to investigate further, often starting with a repeat test and a clinical review, not a diagnosis.

I am taking a ‘testosterone booster’ supplement — should I mention it?

Yes. Many such products contain undisclosed ingredients that alter hormone readings and can carry real side effects. Tell your doctor exactly what you take; they may ask you to stop it for a period before retesting, and they will advise on safety.

At what age should men start PSA testing?

There is no single universal age — guidelines differ, and the decision is individualized based on risk factors such as family history. This is a shared decision with your doctor, who can explain the benefits and downsides of screening at your age.

Can I get my testosterone checked in the afternoon?

It is not ideal. Testosterone follows a daily rhythm and is highest in the morning, so morning draws give the most meaningful result. If you can only manage an afternoon appointment, tell the lab — your doctor needs that context to interpret the number.
