Here is a plain-language explanation of this laboratory report:
Lab Report Summary - JJ Laboratory (Medall Diagnostics)
Patient: Mr. Nagalingam, 65-year-old male
Referring Doctor: Dr. Javid Abdullah, MBBS, D.Diab., MD (Pulmonology)
Specimen Type: Pus (Body Fluid)
Test Performed: Gram's Stain
Report Date: 04-Aug-2026
What the Result Means
Finding: "Many pus cells and few gram positive cocci clusters and singles seen."
Breaking this down:
1. Many pus cells
Pus cells are white blood cells (neutrophils) that the body sends to fight infection. "Many" pus cells means there is an active, significant bacterial infection or inflammatory process at the site where this fluid was collected.
2. Gram-positive cocci in clusters and singles
- Gram-positive = the bacteria retain a purple colour under the Gram stain, which is a basic dye test done rapidly in the lab.
- Cocci = the bacteria are round/spherical in shape.
- Clusters and singles = how these bacteria are arranged. Round bacteria seen in clusters (like a bunch of grapes) are the classic pattern of Staphylococcus species, most commonly Staphylococcus aureus. Singles can also co-exist.
So in simple terms: bacteria consistent with Staphylococcus have been detected in a pus sample, along with heavy inflammation.
Context - Why This Matters for a Lung Patient
Since this is from JJ Lungs / Neo Life Hospital and the referring doctor is a pulmonologist (lung specialist), this pus was likely collected from one of these sources:
- Pleural fluid (fluid around the lungs) - suggesting empyema (pus in the pleural space)
- A lung abscess aspirate
- A drain/tube drainage from a lung or chest infection
This is a serious finding indicating a bacterial infection that needs urgent antibiotic treatment.
What Needs to Happen Next
| Step | Why |
|---|---|
| Culture & Sensitivity (C&S) test | The Gram stain is just a rapid preliminary screening. A bacterial culture will confirm the exact bacteria (e.g., S. aureus, MRSA, etc.) and identify which antibiotics will work best. |
| Immediate physician review | Dr. Javid Abdullah (or the treating team) needs to see this result urgently to start or adjust antibiotic therapy. |
| Antibiotic treatment | Based on the likely Staphylococcus, empirical antibiotics such as anti-staphylococcal penicillins, vancomycin (if MRSA is suspected), or other agents may be considered pending C&S results. |
| Monitor clinical response | Fever, breathing, drainage output, and repeat imaging should be tracked closely. |
Important: This is a preliminary Gram stain result. The Culture & Sensitivity report (usually ready in 48-72 hours) will be the definitive guide to targeted treatment. Please ensure the treating doctor reviews this report without delay.

Finding Sources
Here is a clear explanation of this second report:
Lab Report Summary - ADA Test (JJ Laboratory)
Patient: Mr. Nagalingam, 65-year-old male
Referring Doctor: Dr. Javid Abdullah, MD (Pulmonology)
Specimen: Pericardial Fluid (fluid around the heart)
Method: Spectrophotometry
Report Date: 05-Aug-2026
The Test Result
| Parameter | Your Result | Unit | Reference Ranges |
|---|---|---|---|
| Adenosine Deaminase (ADA) | 154 | U/L | <30 = Normal |
| 30-40 = Suspect | |||
| 40-60 = Strong Suspect | |||
| >60 = POSITIVE | >60 = Positive |
Remark: Kindly correlate clinically
What is the ADA Test?
The Adenosine Deaminase (ADA) test measures the level of an enzyme produced by certain immune cells (T-lymphocytes) that are activated when the body is fighting a specific type of infection - most importantly, tuberculosis (TB).
When TB (or certain other infections) causes inflammation around the heart, the ADA enzyme leaks into the pericardial fluid (the fluid around the heart) in very high amounts.
What Does a Result of 154 U/L Mean?
The normal upper limit is <30 U/L. This patient's result is 154 U/L - more than 5 times the positive threshold of 60 U/L.
This is a strongly positive result. It is a very significant finding that points toward:
- Tuberculous pericarditis (TB infection of the lining around the heart) - this is the most common cause of a markedly elevated ADA in pericardial fluid, especially in India/South Asia
- Less commonly: other bacterial infections, lymphoma, or rheumatoid disease (but a value this high - 154 - is highly specific for TB)
How This Connects to the Previous Gram Stain Report
Reading both reports together for the same patient (Mr. Nagalingam, PID 3844526):
| Report | Finding | Interpretation |
|---|---|---|
| Gram Stain (pus, body fluid) | Many pus cells + gram-positive cocci | Active bacterial infection |
| ADA (pericardial fluid) | 154 U/L (>5x the positive cutoff) | Strongly suggests TB pericarditis |
The patient likely has TB pericarditis with a secondary bacterial infection, or the TB has caused an empyema/pus collection in the chest. This is a serious combined finding.
What Needs to Happen Next - Urgently
- Urgent pulmonology review - Dr. Javid Abdullah needs to see both reports immediately.
- Anti-TB treatment (ATT) - If TB pericarditis is confirmed clinically, a 4-drug anti-TB regimen (HRZE) is started. Corticosteroids are often added to prevent pericardial constriction.
- Echocardiogram - To assess the amount of fluid around the heart (pericardial effusion) and check if the heart is being compressed (cardiac tamponade), which is a medical emergency.
- Culture for TB (AFB culture / GeneXpert) - Confirmatory testing of the pericardial fluid if possible.
- Antibiotic treatment - For the concurrent bacterial infection (as identified on the Gram stain).
Important: An ADA of 154 U/L in pericardial fluid is a medically urgent result. Please make sure the treating doctor is informed as soon as possible. This is not a finding to wait on.
