Most of us visit a doctor only when we feel unwell. But here’s the truth: Many health problems don’t show symptoms in the early stages. Regular health tests can spot these issues early, giving you a chance to act before it’s too late.
Here are the top 5 health tests everyone should take seriously:
1. Blood Pressure Test – Guard Against the Silent Killer
High blood pressure (hypertension) is often called the “silent killer” because it shows no symptoms but quietly damages your heart, brain, kidneys, and eyes.
A quick test can tell you if your numbers are safe:
- Normal: Around 120/80 mmHg
- Elevated: 120–129 / <80 mmHg
- High (Hypertension): 140/90 mmHg or above
Why it matters: Untreated hypertension can lead to heart disease, stroke, kidney failure, and vision problems.
Tip: Even if you feel healthy, check your blood pressure at least once a year. If you have risk factors like stress, obesity, or family history, check it more often.
2. Blood Sugar Test – Catch Diabetes Early
Diabetes often develops quietly, with little to no symptoms in the beginning. A simple blood sugar test can tell you if your levels are normal, prediabetic, or diabetic.
Key numbers to know:
- Diabetes: 126 mg/dL or higher
- Normal (fasting): Below 100 mg/dL
- Prediabetes: 100–125 mg/dL
Why it matters: High blood sugar, if left untreated, can damage your heart, kidneys, nerves, and eyes over time.
Tip: Get your blood sugar checked once a year, especially if you’re overweight, have a family history of diabetes, or live a sedentary lifestyle. Early detection makes diabetes easier to manage.
3. Cholesterol Test – Know Your Heart Risk
Cholesterol is needed by the body, but too much of the “bad” LDL cholesterol can block arteries and raise your risk of heart attack or stroke. A cholesterol test (lipid profile) shows the balance between good (HDL) and bad (LDL) cholesterol.
Key numbers to remember:
- HDL (good): 40 mg/dL or higher
- Total cholesterol: Below 200 mg/dL is ideal
- LDL (bad): Below 100 mg/dL
- Triglycerides: Below 150 mg/dL
Why it matters: High cholesterol often has no symptoms but can seriously harm your heart health.
Tip: Adults over 20 should check cholesterol every 4–6 years. If you have diabetes, obesity, or a family history of heart disease, get tested more often.
4. Complete Blood Count (CBC) – Your Health Snapshot
A CBC test gives a quick overview of your overall health by checking red blood cells, white blood cells, and platelets.
What it can reveal:
- Immune or blood disorders
- Anemia (low red blood cells)
- Infections (high white blood cells)
Why it matters: Many conditions show up first in the blood. A CBC can catch problems early, even before symptoms appear.
Tip: Include a CBC in your routine health checkup once a year, or as recommended by your doctor.
5. Thyroid Function Test – Balance Your Energy
Your thyroid gland controls metabolism, energy, and even mood. If it’s not working properly, you may feel tired, gain or lose weight unexpectedly, or have mood swings.
A thyroid function test (TSH, T3, T4) checks if your thyroid is overactive (hyperthyroidism) or underactive (hypothyroidism).
- TSH (Thyroid Stimulating Hormone): 0.5 – 4.5 mIU/L
- Free T4 (Thyroxine): 0.8 – 2.0 ng/dL
- Free T3 (Triiodothyronine): 2.3 – 4.2 pg/mL
Why it matters: Thyroid problems are common but often overlooked. Detecting them early helps you manage weight, energy, and overall health.
Tip: If you notice unusual tiredness, hair loss, weight changes, or mood issues, ask your doctor about a thyroid test.
Health isn’t just about eating right or exercising—it’s also about keeping track of what’s happening inside your body.
