Tuberculosis (TB) remains one of the most common infectious diseases in Pakistan, especially among children who are unable to produce sputum for testing. In such cases, doctors often rely on the GeneXpert Gastric Aspirate test, a highly advanced molecular diagnostic test used to detect Mycobacterium tuberculosis with exceptional accuracy. This test is performed at Dr. Essa Laboratory & Diagnostic Centre, one of Pakistan’s most trusted and specialized diagnostic facilities known for its precise testing methods, modern equipment, and rapid reporting system.
The GeneXpert technology is widely recommended worldwide because it can detect TB bacteria and rifampicin resistance within a short time. When doctors suspect tuberculosis especially in children, bedridden patients, or those unable to cough up sputum this test becomes extremely valuable. Dr. Essa Lab provides this test with expert sample handling, ensuring accuracy, safety, and reliability at every stage.
This article explains the GeneXpert Gastric Aspirate test price, its purpose, preparation, procedure, report details, and how to conveniently book the test anywhere in Pakistan. By the end, you will clearly understand why Dr. Essa Lab is one of the best choices for GeneXpert testing.
What is the GeneXpert Gastric Aspirate Test?
The GeneXpert Gastric Aspirate test is a molecular diagnostic test used to detect tuberculosis bacteria (TB) using a sample collected from the stomach through gastric aspiration. This method is especially helpful for:
- Children who cannot produce sputum
- Patients who swallow sputum instead of coughing it out
- Cases where sputum smear tests come negative but TB is still suspected
- Early detection of pulmonary TB
The test uses PCR (Polymerase Chain Reaction) technology to rapidly detect the DNA of TB bacteria. GeneXpert also identifies rifampicin resistance, which is important for diagnosing drug-resistant TB.
Doctors commonly recommend the GeneXpert Gastric Aspirate test to diagnose:
- Pediatric tuberculosis
- Suspected pulmonary TB in patients unable to give sputum
- Difficult or unclear TB cases
- Drug-resistant TB
- Treatment monitoring in some cases
It is considered one of the most advanced, accurate, and fast TB diagnostic tools available in Pakistan.
Why is the GeneXpert Gastric Aspirate Test Important?
This test is crucial because detecting TB early can prevent severe complications, long treatments, and transmission to others. Unlike traditional smear or culture tests, which may take days or weeks, GeneXpert provides highly accurate results in a much shorter time.
Key benefits of the test include:
High Accuracy: Detects even low levels of TB bacteria
Fast Turnaround: Results often available within the same day
Drug Resistance Detection: Identifies rifampicin resistance instantly
Kid-Friendly: Ideal for children who cannot give sputum
Non-smear-dependent: Useful when smear tests show negative results
TB is a serious disease, and missing early diagnosis can delay treatment. That is why doctors trust GeneXpert gastrointestinal aspirate testing, especially when dealing with high-risk patients.
When Should You Get a GeneXpert Gastric Aspirate Test?
Doctors may recommend this test if you or your child shows symptoms of tuberculosis or if tuberculosis is suspected but sputum sample collection is difficult.
You may need this test if:
- Your child cannot cough up sputum
- You have persistent cough lasting more than 3 weeks
- There is unexplained fever, especially in children
- Significant weight loss, loss of appetite, or fatigue
- Night sweats occur regularly
- Chest X-ray results suggest TB
- Family history of TB exposure
- Doctor suspects drug-resistant TB
- Routine follow-up is required in complicated TB cases
For children, this test is considered one of the most reliable ways to detect TB early.
How to Prepare for the GeneXpert Gastric Aspirate Test?
Preparing for the test is simple but important. Since the sample is collected from the stomach, certain preparations must be followed:
Fasting Requirement
- The patient must be fasting for at least 4-6 hours before the sample is collected.
- The best time for gastric aspirate is early morning before eating or drinking anything.
Medication Instructions
- Inform the doctor or lab if the patient is taking TB medication.
- Avoid unnecessary medicines unless prescribed.
Clothing & Comfort
- Wear comfortable clothing.
- For children, parents should stay with them during the procedure.
Other Tips
- Follow doctor’s instructions carefully.
- Calm and prepare young children before the test to reduce anxiety.
No complex preparation is needed, but following the above steps helps ensure an accurate result.
How is the GeneXpert Gastric Aspirate Test Performed at Dr. Essa Laboratory?
Dr. Essa Laboratory has trained medical professionals who follow strict protocols for sample collection to ensure comfort, safety, and accuracy.
Step-by-Step Procedure:
Step 1: Patient Preparation
The patient is asked to come in fasting. A nurse explains the procedure and positions the patient properly, usually sitting upright or lying down.
Step 2: Nasogastric (NG) Tube Insertion
A thin, flexible tube (NG tube) is gently passed through the nose or mouth down into the stomach.
This tube allows the collection of gastric fluid containing swallowed sputum.
Step 3: Sample Collection
Once the tube reaches the stomach, a small amount of gastric fluid is aspirated using a syringe.
This fluid often contains swallowed TB bacteria, especially in young children.
Step 4: Sample Processing
The sample is immediately transferred to the GeneXpert cartridge.
Dr. Essa Lab uses advanced GeneXpert automated testing systems that:
- Extract DNA
- Detect TB bacteria
- Identify rifampicin resistance
Step 5: Reporting
Reports are typically available same day or within 24 hours.
Why Dr. Essa Lab is Trusted for this Test?
- Highly trained technicians
- Modern GeneXpert machines
- Strict infection control
- Child-friendly environment
- Fast, reliable results
This ensures maximum accuracy and comfort for pediatric and adult patients.
GeneXpert Gastric Aspirate Report & Normal Values
GeneXpert reports are usually simple and easy to understand. The report includes:
| Parameter | Normal Value / Expected Result |
| MTB Detection | Not Detected |
| Rifampicin Resistance | Not Detected |
| TB DNA Levels | Low / Medium / High (if detected) |
Understanding the Report
- Not Detected: No TB bacteria were found.
- Detected: TB bacteria are present, and treatment is required.
- Rifampicin Resistance Detected: Indicates possible drug-resistant TB (MDR-TB).
- Trace levels: Very low levels of TB; clinical correlation needed.
Only a doctor can interpret the results accurately based on symptoms, history, and X-rays.
Understanding Abnormal Results
If the report shows TB Detected, it means the bacteria responsible for tuberculosis are present. This result requires immediate medical attention.
Possible Causes of Abnormal Results
- Active pulmonary tuberculosis
- Drug-resistant TB
- Swallowed sputum containing TB bacteria
- Complicated or advanced TB cases
- Recent exposure to a TB-positive patient
If Rifampicin Resistance is Detected
This indicates drug-resistant tuberculosis, which requires specialized treatment from a chest specialist or infectious disease expert.
Next Steps After Abnormal Results
- Repeat testing if advised
- Chest X-ray or CT scan
- Culture and sensitivity tests
- Start anti-TB medicine under medical supervision
Early diagnosis and treatment significantly improve recovery chances.
How to Improve Lung Health Naturally (Helpful Tips)
