Somebody will offer you an eighty-test "full body" package for a very attractive price. It will include things you have never heard of. You will feel thorough for having done it.

We want to make an unfashionable argument: the number of tests in a package is not a measure of its value, and past a point it actively works against you.

Every test has a chance of producing an abnormal result that means nothing — a small cyst, a borderline figure, a shadow. Each of those has to be chased. The chasing involves more scans, more waiting, sometimes a needle, and a period of genuine fear. Occasionally it ends in a procedure that was never needed. We see this every month, and the patient's health was never at risk — only their peace of mind and their money.

The right question is not "how many tests?" It is "would the result change what we do?"

So here is our honest answer: the tests that genuinely matter after forty, the ones that matter for you specifically, and — the part nobody writes down — the ones you can skip.

Why forty

Not because something switches on at your birthday. Because of where the curves bend.

Blood pressure, blood sugar, cholesterol and several cancers all start becoming meaningfully more common through the forties. And in Indians, cardiac and metabolic disease appears roughly a decade earlier than in Western populations — which is why screening advice copied from American or European websites tends to start too late for us.

The other reason is the one running through everything we have written on this site: these conditions are silent at the stage when treating them is easy. High blood pressure produces no symptoms. Early diabetes produces no symptoms. Early kidney damage produces no symptoms. A small breast lump does not hurt. By the time there is something to feel, the easy window has usually closed.

The core set — everybody over forty

These are the tests we would want done for any patient over forty, and most of them cost very little.

1. Blood pressure. At every medical visit, and at least once a year regardless. This is the cheapest, highest-value measurement in medicine and it is routinely skipped.

2. Blood sugar — fasting glucose and HbA1c. HbA1c shows your average over roughly three months, so it does not depend on what you ate yesterday. It also identifies prediabetes, which is the stage at which the whole thing is still reversible.

3. Lipid profile. Total cholesterol, LDL, HDL, triglycerides. Every three to five years if normal; annually if it is not, or if you have diabetes, hypertension or a family history of early heart disease.

4. Waist measurement — more useful than your weight. And the Indian numbers are not the Western ones. For Indians, a waist above 90 cm in men and 80 cm in women signals increased risk, and BMI thresholds are lower too — overweight from 23 rather than 25. Most people measure themselves against the wrong scale and conclude they are fine. Measure at the level of the navel, standing, after breathing out normally.

5. Complete blood count. Picks up anaemia, which is extremely common in Indian women and very often dismissed as "weakness".

6. Kidney function — creatinine with eGFR, and a urine routine. Protein appearing in the urine is one of the earliest signs of kidney damage, and it appears long before any symptom. Essential if you have diabetes or hypertension.

7. Liver function. Fatty liver has become extremely common, including in people who do not drink and do not look overweight. It is silent, it is detectable, and at an early stage it is reversible.

8. Thyroid — TSH. Common, particularly in women, easily missed because the symptoms are vague — tiredness, weight change, low mood — and easily treated once found.

9. Vitamin D and B12 — once, then only if indicated. Deficiency is widespread enough in India that one baseline measurement is reasonable. What is not reasonable is repeating them every six months out of habit. Test, treat if low, recheck as advised, then leave them alone.

10. ECG. A baseline at forty, repeated as your doctor advises. Its real value is often comparison — an ECG means much more when there is an older one to hold it against.

11. An eye examination by an eye specialist, and a dental check. Neither is done here, both are worth doing, and both are routinely postponed for years.

Cancer screening — and this is where the real gains are

For women

Breast. A clinical breast examination each year, and mammography from the age of forty, at the interval your doctor advises. Breast cancer is the commonest cancer in Indian women, it appears about a decade earlier here than in the West, and the difference between early and late diagnosis is enormous.

Cervical. A Pap smear every three years, or an HPV test every five, between the ages of thirty and sixty-five. This is the single most under-used test in Indian women's health. Cervical cancer is one of the few cancers that is very largely preventable, because screening catches changes years before they become cancer — and most women in this country are never offered it.

For men

Prostate. We are going to be honest rather than tidy here: PSA testing is genuinely contested. It finds cancers that would never have caused harm, and treating those causes real side effects. It is a conversation to have with your doctor from around fifty — earlier with a family history — not a box to tick automatically.

For everyone

Bowel. From forty-five to fifty, either a stool test for hidden blood each year or a colonoscopy every ten years. Bowel cancer is rising in India and in younger people. If you have ever been told your rectal bleeding is piles without being examined properly, read that sentence again.

Mouth. A simple examination of the mouth and tongue, which takes a minute. India has among the highest rates of oral cancer in the world, driven by tobacco, gutkha and paan masala, and it is one of the few cancers you can literally see early. If you use tobacco in any form, this is not optional and no package line item matters more.

Lungs. Low-dose CT screening applies to heavy long-term smokers in specific age bands, not to the general population. Ask if it applies to you.

Extra tests, if this applies to you

What you probably do not need

This is the section that gets left out of brochures, and it is the reason we wrote this article.

Tumour marker panels as a screening test. CA-125, CEA, CA 19-9, AFP and similar are frequently sold in "cancer screening" packages to people with no symptoms. They are not validated for screening healthy people. They are raised by many harmless conditions, they are normal in plenty of people who do have cancer, and a mildly abnormal result in a well person reliably produces months of anxiety and a chain of investigations that usually find nothing. These tests are useful for monitoring a cancer that is already diagnosed. That is a different job.

Whole-body CT or PET scans as a screening test. Significant radiation, no demonstrated benefit for people at average risk, and a very high rate of incidental findings that then have to be chased.

A treadmill test when you have no symptoms and no risk factors. False positives are common, and a false positive leads to an angiogram that was never needed.

The eighty-test panel. Many of the tests in it would not change anything we do. The genuinely useful ones are in the core list above, and they are not expensive.

Vitamin D every six months. Test, correct it, recheck once as advised, stop.

A chest X-ray every year if you have no symptoms and have never smoked.

Our principle, stated plainly: a test is worth doing when the result would change what happens next. If no plausible result would change anything, the test is not caution — it is cost and risk with no upside.

How often — a simple schedule

Getting it right on the day
1. Fast for 10–12 hours for sugar and lipids — water is fine
2. Take your regular medicines as usual unless specifically told otherwise. Do not skip your BP or thyroid tablet to "get a true reading" — that is not how either works
3. Bring your old reports. This matters more than people realise. A creatinine of 1.2 means one thing on its own and something quite different if it was 0.8 two years ago. Trends carry more information than single values
4. First morning urine sample where asked
5. Avoid heavy exercise and alcohol for 24 hours before a lipid profile
6. Women: do not schedule a Pap smear during your period
7. Write down your family history before you come — who, which condition, at what age. People reliably forget half of it in the consulting room

When the report comes back

Take it to a doctor rather than to the internet. A "borderline" value is information, not a verdict, and most abnormal results in a well person are either insignificant or easily corrected.

Two things to expect: some values will be flagged high or low that need nothing at all, and a normal report today is not a guarantee for the next five years. Screening is a repeated process, not a certificate.

At Shree Kkasturi Medicare, our preventive health check-up packages are built around the tests above, with a consultation to go through the results — because a report handed over without someone explaining it is only half of what you paid for.

Frequently asked questions

Q. I feel completely fine. Why should I get tested? A. Because the conditions worth finding — raised blood pressure, early diabetes, early kidney damage, a small breast lump — produce no symptoms at the stage when they are easiest to treat. Feeling fine is exactly the state in which screening is useful. Once you feel unwell, you are not screening any more; you are investigating.

Q. Is a bigger package better? A. No. More tests mean more incidental abnormalities to chase, with more anxiety, cost and occasionally real harm. What matters is whether the right tests are included for your age, sex and risks, and whether someone sits down and explains the results.

Q. Should I get tumour markers done to screen for cancer? A. Not as a screening test in a healthy person. They are not reliable for that purpose and they generate a great deal of unnecessary alarm. The cancer screening with real evidence behind it is in the list above — breast, cervical, bowel and oral.

Q. My sugar is "borderline". Does that mean nothing yet? A. It means a great deal. Prediabetes is the stage at which weight loss, dietary change and exercise can genuinely reverse the trajectory. It is the most valuable finding a check-up can produce, and it is the one most often ignored because it does not come with a diagnosis attached.

Q. How often should I actually do this? A. For most healthy people over forty, annually for the core tests, with cancer screening at the intervals in the table. Your doctor may shorten that if something needs watching.

Q. Should my parents in their seventies still be screened? A. Some things yes, some no. Blood pressure, sugar, kidney function, vision, hearing and fall risk remain valuable. Some cancer screening becomes less useful in later life, particularly where other conditions would dominate the outcome. This is a conversation worth having specifically rather than applying a package designed for a forty-year-old.

Q. I had a full check-up two years ago and everything was normal. Can I skip this year? A. Blood pressure, sugar and weight are worth checking annually regardless — they change. A normal report two years ago says what was true two years ago.
