COVID-19 test cost in Bangalore: antigen vs RT-PCR (2026)
Two main COVID-19 tests remain in use -- rapid antigen and RT-PCR. Here is what each costs at Bangalore labs, how accurate they are, and when to use which.
$## Antigen test vs RT-PCR: which is which?
Rapid Antigen Test (RAT): Detects proteins from the SARS-CoV-2 virus directly. Results are available within 15 to 30 minutes. Highly specific (few false positives) but less sensitive than RT-PCR (more false negatives, particularly in early infection or low viral load). Best used when you have symptoms and want a quick result.
RT-PCR (Reverse Transcriptase Polymerase Chain Reaction): Detects the genetic material (RNA) of the virus. More sensitive than antigen tests -- it can detect infection even at lower viral loads. Results take 4 to 24 hours depending on the lab. The standard test for travel requirements and official documentation.
Typical prices at Bangalore labs
Rapid Antigen Test: Rs. 150 to 500
Widely available. Most labs that were doing high volumes during the pandemic have maintained the capacity for ongoing demand.
RT-PCR: Rs. 300 to 900
Government-regulated pricing has brought costs down significantly since the pandemic peak. Independent labs certified for COVID testing charge Rs. 300 to 600 in most cases.
Home collection for RT-PCR: Usually available with an additional Rs. 100 to 200 collection charge, or free above a minimum order value.
Preparation
Do not eat, drink, or use mouth wash for 30 minutes before the test. The sample is collected via a nasopharyngeal swab (a swab inserted into the nasal passage), which is uncomfortable briefly but not painful.
How long do results take?
Rapid antigen: 15 to 30 minutes at the collection point. RT-PCR: 4 to 24 hours. Most certified labs in Bangalore return results within 6 to 12 hours.
When to get tested
Symptomatic individuals: either test is appropriate. A negative antigen test with ongoing symptoms warrants an RT-PCR to rule out a false negative.
For travel: check the destination's entry requirements. Most require a negative RT-PCR within a specified window (48 to 72 hours before travel). Antigen test results are generally not accepted for international travel.
For close contact exposure without symptoms: RT-PCR 4 to 5 days after exposure is more reliable than testing immediately.
