Heart disease remains one of the leading causes of death in India—yet many risks are preventable with timely testing. Modern laboratory screening lets you spot problems early, well before symptoms appear.

At Nobel Micropath Laboratory, we emphasize preventive care with accurate reports, clinician-friendly formatting, and convenient home sample collection across Surat. Explore all blood tests in Surat we offer.

1) Lipid Profile (Cholesterol Panel)

Measures Total Cholesterol, HDL (“good”), LDL (“bad”), and Triglycerides. Unfavourable ratios increase the risk of plaque build-up and heart attack.

  • Why it matters: High LDL / low HDL strongly correlates with cardiovascular risk.
  • Prep: Prefer 10–12 hours fasting for best accuracy.
  • How often: Every 6–12 months; more often if on treatment.

2) High-Sensitivity C-Reactive Protein (hs-CRP)

A sensitive marker of vascular inflammation. Persistent elevation can indicate higher risk of cardiac events, especially in diabetes or obesity.

  • Why it matters: Inflammation accelerates atherosclerosis even when cholesterol looks “normal”.
  • Prep: No fasting required. Avoid testing during acute infections.

3) Blood Glucose & HbA1c

High glucose silently damages blood vessels and the heart. HbA1c reflects your average blood sugar over the past 2–3 months.

  • Why it matters: Diabetes & pre-diabetes markedly increase cardiac risk.
  • Prep: FBS requires ~8 hours fasting; HbA1c does not.

4) Thyroid Function Test (TFT)

Thyroid hormones affect metabolism and heart rhythm. Overactive/underactive thyroid can cause palpitations, cholesterol shifts, or blood-pressure changes. Regular TFT screening helps catch issues early.

  • Why it matters: Thyroid imbalance can aggravate arrhythmias and lipid levels.
  • Panel: TSH, FT3, FT4 (as advised by your physician).

5) Electrolytes Panel

Sodium, potassium, and chloride play a key role in cardiac rhythm. Even minor imbalances can trigger palpitations, cramps, or fatigue.

  • Why it matters: Disturbances may cause or worsen arrhythmias.
  • Prep: No fasting required unless clubbed with fasting tests.
