The RT-PCR (Reverse Transcription Polymerase Chain Reaction) test is a highly sensitive molecular diagnostic test used to detect an active infection with SARS-CoV-2, the virus responsible for COVID-19.

This test identifies specific genetic material (RNA) of the virus by amplifying it through multiple cycles to ensure even trace amounts can be detected. RT-PCR is considered a gold standard method for confirming COVID-19 infection due to its high accuracy.

Samples are commonly collected via a nasal or throat swab. Some test kits also support saliva samples. At-home test kits are available, allowing users to self-collect and send samples to a lab, or use rapid devices that provide results without lab processing.

Orange Health Labs enables residents of Bangalore to conveniently book RT-PCR tests with home sample collection for fast and safe COVID-19 diagnosis.

The RT-PCR test for COVID-19 is usually cost at Rs. 750/- This includes home sample collection. Prices may vary based on city,

Fasting is not required for the RT-PCR test. However, a government-issued ID card (preferably Aadhar) is mandatory for identity verification.

Who Should Get This Test?

• Individuals with COVID-19 symptoms

• Those exposed to a confirmed COVID-19 case

• Travelers or patients undergoing procedures requiring pre-test clearance

• A swab will be inserted into your nose or throat to collect a sample

• You may feel slight discomfort or a gag reflex, but the procedure is brief

• Your sample is sealed and sent to a lab

• Results are usually shared within 2 days via email or WhatsApp

Your healthcare provider may recommend an RT-PCR test for COVID-19 if you exhibit symptoms or have been exposed to the virus.

Common symptoms:

• Fever or chills

• Cough or sore throat

• Shortness of breath or difficulty breathing

• Fatigue and muscle aches

• Loss of taste or smell

• Headache or congestion

• Nausea, vomiting, or diarrhea

RT-PCR tests are also advised for:

• Pre-travel screening

• Hospital admissions or surgeries

• Return-to-work clearance

• Contact tracing or exposure events

If symptomatic, consult your healthcare provider even if you are vaccinated, as breakthrough infections are possible.

RT-PCR results will indicate whether SARS-CoV-2 genetic material was detected in your sample.

Possible results include:

Positive – You currently have an active COVID-19 infection. Isolate immediately, follow medical guidance, and notify close contacts.

Negative – No viral RNA was detected. However, this does not rule out infection, especially if exposure was recent or symptoms persist.

A negative result may be due to:

• Early testing post-exposure

• Low viral load

• Improper sample collection

Even if you test negative, you may become infected later. Continue to follow preventive measures like mask-wearing, physical distancing, and hand hygiene.

If symptoms persist after a negative result, consult your doctor for repeat testing or additional evaluations. Related tests may include:

• Anti-SARS-CoV-2 IgG antibody test

• Rapid antigen test (RAT)
