10 Blood Tests Every Adult Over 35 Should Consider

Most people over 35 in Srinagar receive a basic cholesterol test at best. But silent disease processes — atherosclerosis, insulin resistance, thyroid dysfunction, vitamin deficiency — are already underway. These 10 blood tests give you a complete picture before symptoms appear.

Why 35 is the right age to start comprehensive testing

Thirty-five marks a meaningful biological transition that makes comprehensive testing genuinely worthwhile. Cardiovascular risk begins increasing more steeply, particularly for men. Insulin resistance — the precursor to type 2 diabetes — typically begins manifesting in the mid-30s for at-risk individuals. Thyroid dysfunction rates increase with age and are commonly missed for years. Vitamin D and B12 deficiency, very prevalent across Kashmir due to climate and dietary patterns, compound over time and cause harm that accumulates silently. Starting comprehensive testing at 35 gives you a baseline and the maximum opportunity to intervene before irreversible damage accumulates. All ten tests in this guide are available through home sample collection in Srinagar — no hospital trip required.

Tests 1 and 2: Full lipid panel and ApoB

The full lipid panel — total cholesterol, LDL, HDL, and triglycerides — is the foundation of cardiovascular risk assessment. Fasting 8 to 12 hours is required; recommended every 3 to 5 years if normal, annually if elevated or at risk. However, standard LDL-C has a fundamental limitation: it measures the cholesterol content inside particles, not the particle count. For people with high triglycerides, diabetes, or metabolic syndrome — all increasingly common in Kashmir — LDL-C frequently underestimates real cardiovascular risk. This is where Apolipoprotein B (ApoB) becomes essential. ApoB counts every atherogenic particle in the blood — a far more accurate cardiovascular risk marker in people with metabolic dysfunction. No fasting required; test annually if elevated or at risk. For the full comparison: ApoB vs LDL — which is the better predictor of heart disease?

Tests 3 and 4: HbA1c and Lipoprotein(a)

HbA1c measures your average blood sugar over the past two to three months in a single measurement — far superior to a single fasting glucose test that can be influenced by one day's eating. An HbA1c of 5.7 to 6.4% indicates pre-diabetes — a completely asymptomatic window when intervention can prevent or significantly delay full type 2 diabetes. No fasting required; recommended every 3 years if normal, annually if pre-diabetic or at risk. See our guide: managing diabetes at home in Kashmir. Lipoprotein(a) is a genetically determined cardiovascular risk factor completely absent from the standard lipid panel, present in elevated levels in approximately one in five people, and unaffected by diet, exercise, or statins. It is one of the most important explanations for why apparently healthy people with normal cholesterol have heart attacks in their 30s and 40s. The Lp(a) test requires no fasting and typically needs to be done only once in a lifetime. Full guide: Lipoprotein(a) test in Srinagar.

Tests 5 and 6: Thyroid panel and Vitamin D

The thyroid panel — TSH with Free T3 and T4 — tests the function of the thyroid gland, which controls metabolism, energy, weight, mood, and heart rate. Hypothyroidism is one of the most underdiagnosed conditions in India and its symptoms overlap so completely with normal life — fatigue, weight gain, feeling cold, hair loss, brain fog — that most people attribute them to stress or ageing. Iodine deficiency, historically prevalent in mountainous Kashmir, predisposes to thyroid dysfunction. No fasting required; every 3 to 5 years if normal. Vitamin D (25-OH) is possibly the single most important micronutrient test for Kashmiris. Kashmir's geographic latitude, extensive cloud cover, long Chilla Kalan winters, traditional clothing patterns, and dietary patterns low in vitamin D-rich foods combine to make deficiency extraordinarily common — studies suggest 60 to 80% of people in Kashmir are deficient or insufficient. Beyond bones, vitamin D deficiency is associated with increased cardiovascular risk, impaired immunity, and increased cancer risk. Test annually in Kashmir.

Tests 7 and 8: hs-CRP and Homocysteine

High-sensitivity CRP measures systemic inflammation — an independent cardiovascular risk factor that operates entirely separately from cholesterol. People with elevated hs-CRP are at significantly higher cardiovascular risk even with completely normal LDL cholesterol. The JUPITER trial demonstrated that statin therapy significantly reduced cardiovascular events in people with normal LDL but elevated hs-CRP — making this marker clinically actionable. Measure when healthy rather than during acute illness; no fasting required. Homocysteine is an amino acid that, when elevated, directly damages blood vessel walls and independently raises cardiovascular and stroke risk. It is closely linked to B12 and folate deficiency — both common in Kashmir, especially among vegetarians. Elevated homocysteine is highly treatable with B-vitamin supplementation, making it one of the most clinically satisfying findings in preventive medicine. No fasting required. Both tests are available via home collection in Srinagar.

Tests 9 and 10: Vitamin B12 and Complete Blood Count

Vitamin B12 deficiency is extremely common in Kashmir, particularly among vegetarians and anyone taking metformin — a common diabetes medication that impairs B12 absorption. Deficiency causes anaemia, neurological symptoms, elevated homocysteine raising cardiovascular risk, and profound fatigue. The complete blood count provides the full picture of all blood cell populations — red cells assessing for anaemia, white cells reflecting immune function, and platelets assessing clotting. It also flags early signs of blood disorders including leukaemia. No fasting required for either test; annually for menstruating women, every 2 to 3 years for men. For elderly patients managing multiple chronic conditions, our elderly care services and home nursing service can provide ongoing support around regular monitoring.
