📖About PCR Testing
Polymerase chain reaction (PCR) testing is a highly sensitive laboratory technique that detects the genetic material of a specific virus or bacterium in a patient sample, making it the gold standard for confirming many infectious diseases including COVID-19, tuberculosis and various sexually transmitted infections. The technique works by amplifying tiny amounts of target genetic material millions of times over, allowing detection even when the pathogen is present in very small quantities. This high sensitivity makes PCR far more accurate than rapid antigen tests for confirming infection, particularly in patients with mild symptoms or early in the course of illness. The main trade-off is a longer turnaround time, as samples typically need to be processed in a specialised laboratory rather than read immediately at the point of care.

🔬How the Treatment is Performed
- 1A sample is collected from the relevant site, such as a nasal or throat swab, blood, sputum or other body fluid, depending on the suspected infection. The sample is transported to a laboratory where the genetic material of the target pathogen, if present, is extracted and amplified through repeated cycles of a specialised reaction to reach detectable levels. The amplified material is then analysed to confirm the presence and, in some cases, the quantity of the pathogen, with results reported back to the ordering physician.
📝Pre-Treatment Preparation
- 1Consult a Infectious Diseases specialist to confirm suitability for PCR Testing
- 2Complete all pre-treatment investigations as directed — blood tests, imaging, ECG, or specialist clearance
- 3Disclose all current medications, supplements, and allergies to your treating physician
- 4Fast (nil by mouth) for 6–8 hours if the treatment involves anaesthesia or sedation
- 5Arrange for a responsible adult to accompany you, especially for procedures requiring sedation
- 6Follow all specific pre-treatment instructions issued by your care team regarding diet or medication changes

⚠️Possible Side Effects & Risks
- 1Mild discomfort during sample collection depending on the site, minimal risk of bleeding or bruising with blood-based samples, no significant risk otherwise
🩹Recovery & Aftercare
- 1No recovery time is needed since the test involves only sample collection. Patients can resume normal activities immediately after providing the sample. Results guide the physician's decisions on treatment, isolation or further investigation once available.
