Knowing which blood tests men should get, and when, is the difference between catching a problem early and finding out too late. Most men only get a blood test when something’s already wrong, which is backwards. The entire value of bloodwork is catching problems before you feel them (the rising blood sugar, the creeping cholesterol, the quietly low testosterone) while they’re still easy to fix. Many of the conditions that shorten men’s lives announce themselves in a blood panel years before they cause symptoms.
The problem is knowing what to ask for. Walk into a clinic and “I’d like a check-up” can mean anything. This guide lays out the blood tests that matter for men, what each one tells you, and how the priorities shift by age.
One test most standard panels leave out is lipoprotein(a); our Lp(a) test guide explains why you only need it once.
The Core Panel: Blood Tests Men Should Get First
Regardless of age, these are the foundational tests worth getting periodically. Think of them as your baseline dashboard.
Lipid panel (cholesterol). Measures total cholesterol, LDL (“bad”), HDL (“good”), and triglycerides. This is central to assessing heart disease risk, which is the leading killer of men. A standard recommendation is checking every 4 to 6 years from your 20s, more often if you have risk factors or elevated results. Pay attention to the LDL and the triglyceride numbers in particular. If you can, ask for ApoB as well, which counts the particles that drive plaque (see the ApoB blood test).
Blood glucose / HbA1c. Fasting blood glucose and HbA1c (a measure of your average blood sugar over ~3 months) screen for prediabetes and type 2 diabetes. Type 2 diabetes is common, often silent in its early stages, and far easier to reverse when caught early. Increasingly important from your 30s and 40s onward, especially if you carry excess weight. A continuous glucose monitor shows more detail, though for most men without diabetes it’s optional (see CGMs for non-diabetics).
Complete blood count (CBC). A broad screen of your red cells, white cells, and platelets. It can flag anaemia, infection, and a range of other issues, and it’s a standard part of any general check-up.
Comprehensive metabolic panel (CMP). Checks kidney function, liver function, blood proteins, and electrolytes. Useful for spotting kidney or liver problems early, which is relevant given alcohol’s effect on the liver and the kidney’s role in blood pressure.
Vitamin D. Given how common deficiency is in men, and its links to fatigue, immunity, bone health, and mood, vitamin D is a worthwhile addition, particularly if you get limited sun. We cover this in depth in our guide to vitamin D deficiency in men.
Tests That Become Important With Age and for Men Specifically
Testosterone. If you have symptoms of low testosterone (fatigue, low libido, loss of muscle, low mood, poor morning erections), a testosterone test is worth requesting. Ideally measured in the morning when levels peak, and interpreted alongside symptoms rather than the number alone. Becomes more relevant from the late 30s onward as levels naturally decline. Ask about both total and free testosterone.
PSA (prostate-specific antigen). A blood marker related to prostate health, used in screening for prostate issues including cancer. This is a discussion to have with your doctor rather than an automatic test, because PSA can be raised by a benign enlarged prostate, not just cancer, and screening has both benefits and limitations. Generally a conversation for men from around age 50 (earlier with family history). We cover the nuances in our guide to the PSA test.
Thyroid function (TSH). Checks how your thyroid is working (see thyroid symptoms in men). An underactive thyroid can cause fatigue, weight gain, low mood, and brain fog, symptoms men often attribute to stress or ageing. Worth testing if you have those symptoms.
Inflammatory markers (e.g. hs-CRP). High-sensitivity C-reactive protein measures inflammation and can add information about cardiovascular risk. Often included in more thorough cardiovascular assessments.
A Rough Guide by Decade
This is general orientation, not a prescription; your doctor tailors testing to your personal and family history.
In your 20s to 30s: Establish your baseline. Lipid panel, blood glucose, CBC, CMP, vitamin D. Testosterone if you have symptoms. This baseline is valuable: it’s what future results get compared against.
In your 40s: Everything above, with more attention to blood sugar/HbA1c and cholesterol as cardiovascular and metabolic risk climbs. Testosterone becomes more relevant. Begin discussing prostate screening timing with your doctor.
In your 50s and beyond: Continue the core panel more regularly. Have the PSA conversation. Keep close watch on cardiovascular and metabolic markers, since this is when risk accelerates. Thyroid and other targeted tests as symptoms warrant.
| Age | Core tests | Add based on age and symptoms |
|---|---|---|
| 20s to 30s | Lipid panel, blood glucose, CBC, CMP, vitamin D | Testosterone if you have symptoms. Establishes the baseline future results compare against |
| 40s | All of the above, with more attention to blood sugar/HbA1c and cholesterol | Testosterone becomes more relevant; begin discussing prostate screening timing |
| 50s and beyond | Core panel more regularly; close watch on cardiovascular and metabolic markers | The PSA conversation; thyroid and other targeted tests as symptoms warrant |
How to Get the Most From Your Bloodwork
A few practical tips:
- Fast if required. Some tests (lipids, fasting glucose) need 8 to 12 hours of fasting. Confirm beforehand so you don’t have to repeat them.
- Test in the morning for anything affected by daily rhythm, especially testosterone.
- Keep your results. Track them over time: trends matter more than single snapshots. A cholesterol number creeping up year over year is more informative than one reading.
- Ask for your actual numbers, not just “everything’s normal.” Many results sit within the “normal” range but at an edge worth watching.
- Interpret in context. A number is just a number until it’s read alongside your symptoms, history, and other markers. That’s your doctor’s job, but understanding the basics helps you ask better questions.
Bloodwork pairs naturally with the other numbers worth tracking: your blood pressure, resting heart rate, body fat percentage, and waist-to-height ratio. Together they form a useful picture of where your health stands and where it’s heading.
How to Read Your Results Without Panicking
Most men open a set of results, scan for anything highlighted in red or yellow, and start worrying about that one line. It helps to understand how those ranges are built before you do.
What a reference range is
A laboratory reference interval is normally set as the central 95 percent of values from a group of apparently healthy people, running from the 2.5th to the 97.5th percentile, and the implication is easy to miss: by construction, roughly one in twenty perfectly healthy people falls outside any given range. Order a panel with ten separate markers on it and the odds that at least one comes back flagged are high even when nothing whatsoever is wrong with you.
This is not a hypothetical problem. The number of results that land outside the normal range substantially exceeds the number that turn out to be clinically meaningful.
Normal is not the same as optimal
Reference ranges describe how a population is distributed. They are not a statement about what is ideal for you, and they move as the evidence does. The thresholds for blood pressure have been lowered over the years, the range for thyroid stimulating hormone has been narrowed, and target cholesterol values have come down. A result sitting just inside the range is not automatically fine, and one sitting just outside it is not automatically a problem.
What to do with a borderline result
Three things are worth holding onto.
A single reading is a data point, not a diagnosis. Most borderline values get repeated before anyone acts on them, because biological variation, a recent illness, a hard training session or what you ate the day before can all move numbers around.
Trends beat snapshots. A marker that has climbed steadily across three annual tests while staying technically in range tells you far more than a single value sitting slightly outside it. Keep your old results and bring them with you.
Interpret the panel, not the line. Markers move together in patterns, and a doctor reading the whole picture alongside your symptoms and history will reach a different conclusion than you will reading one highlighted row. This is the main weakness of ordering panels privately and interpreting them yourself: you get the numbers without the context that makes them mean anything.
FAQ: Blood Tests Men Should Get
What blood tests should a man get annually?
There’s no single universal list, but a core panel (lipid panel, blood glucose/HbA1c, CBC, and a metabolic panel) covers the essentials, with frequency depending on age and risk. Vitamin D, testosterone, thyroid, and PSA are added based on symptoms and age.
At what age should men start getting blood tests?
Establishing a baseline in your 20s or 30s is valuable. Cholesterol screening is often recommended from the 20s every few years, with more comprehensive and frequent testing as you move through your 40s and 50s.
Do I need to fast before a blood test?
For some tests, yes: lipid panels and fasting glucose typically require 8 to 12 hours of fasting. Always confirm with the clinic, since fasting requirements vary by test.
Should every man get a PSA test?
Not automatically. PSA screening has benefits and limitations, and an elevated result can come from a benign enlarged prostate. It’s best discussed with your doctor, generally from around age 50 or earlier with family history.
When should I test testosterone?
If you have symptoms like persistent fatigue, low libido, lost muscle, or low mood, particularly from your late 30s onward. Test in the morning when levels peak, and have it interpreted alongside your symptoms.
The Bottom Line on Blood Tests Men Should Get
Blood tests are how you catch the silent problems (high cholesterol, rising blood sugar, low testosterone, thyroid issues) while they’re still easy to address. Every adult man benefits from a core panel of cholesterol, blood sugar, a complete blood count, and a metabolic panel, with vitamin D, testosterone, thyroid, and PSA added based on age and symptoms. Establish your baseline early, keep your numbers, track the trends, and use them to have better conversations with your doctor. It’s one of the highest-leverage, lowest-effort things a man can do for his long-term health, but only if you don’t wait until something’s already wrong.
This article is for informational purposes only and does not constitute medical advice. Which tests are right for you depends on your individual health, history, and risk factors; consult a qualified healthcare professional. One test worth asking about that rarely appears on a standard panel is ApoB (see the ApoB blood test).
