In today’s world, where viruses, infections, and stress are part of our everyday lives, your immune system is your body’s first and most vital line of defense. You may eat well, exercise regularly, or take supplements, but how do you really know if your immunity is strong enough to fight off illness?
That’s where science steps in.
With HealthChek’s Immunity Scorecard, you can measure and understand your body’s internal defense mechanisms using simple, evidence-based lab tests. These tests don't just give you numbers — they provide a deep insight into how your immune system is performing and where it may need support.
Let’s break down the most important lab tests that reveal your immune health status, and why they matter more than ever.
1. Complete Blood Count (CBC) with Differential
This is the most basic and essential test to assess immunity.
What it tells you:
-
White Blood Cell (WBC) count — your body’s infection fighters
-
Neutrophils, Lymphocytes, Monocytes — types of immune cells
-
If your immune response is underactive or overactive
?? Low WBC? You may have weak immunity.
?? High WBC? Your body could be fighting infection or inflammation.
2. Vitamin D (25-Hydroxy Vitamin D)
Vitamin D isn’t just for bones — it's a critical immune system modulator.
Why it matters:
?? 80% of Indians are Vitamin D deficient. Low levels weaken your immunity silently.
3. Immunoglobulin Test (IgG, IgA, IgM)
This test checks the core proteins your body uses to fight bacteria and viruses.
What it shows:
-
IgG: Long-term protection (past infections)
-
IgA: Mucosal immunity (nose, throat, gut)
-
IgM: Immediate response to current infections
?? Low levels may mean compromised immunity or immune deficiency disorders.
4. C-Reactive Protein (CRP) and ESR
These are inflammation markers. If your immune system is fighting hard, inflammation levels rise.
Why it’s important:
?? High CRP levels are also linked to heart disease and diabetes.
5. Nutritional Panel (Iron, Zinc, B12, Folate)
Your immunity depends heavily on proper nutrition.
Nutrients that impact your immune response:
-
Zinc: Essential for white blood cell production
-
Iron: Supports immune cell function
-
Vitamin B12 & Folate: Help form infection-fighting cells
?? Even mild deficiencies can reduce your immune efficiency drastically.
6. Lymphocyte Subset Panel (CD4, CD8 Counts)
This is an advanced immune system test to evaluate T-cell activity, especially used in:
?? CD4: The "commander" of immune responses. Low levels = immune suppression.
7. Cortisol Test (Stress Hormone)
High levels of chronic stress suppress immune function.
Why check cortisol:
?? Chronic stress = lower T-cell response = higher infection risk.
Bonus: Allergy Panel / Food Sensitivity Test
If your immune system is overreacting to harmless substances, it’s a sign of immune imbalance.
-
IgE-based tests help identify triggers
-
Overactive immunity can cause skin rashes, asthma, sinusitis, etc.
Why Lab Tests Matter More Than Symptoms
Many people feel healthy but walk around with suppressed or overworked immune systems. Symptoms like:
Lab tests cut the guesswork and give you real data about your body's internal defense army.
