COVID-19 PCR Test

It detects the genetic material of SARS-CoV-2, the virus that causes COVID-19, from a single nasal swab by real-time RT-PCR. The report is qualitative: the virus was either detected in that sample or it was not. It does not measure antibodies or tell you about a past infection.

An antigen strip looks for viral proteins and needs a reasonable amount of virus present to turn positive. PCR copies viral genetic material many times over first, so it picks up infection earlier and at far lower levels. That is why a PCR is often used to check a negative home test in someone with clear symptoms.

Not immediately. The virus needs time to multiply in the nose and throat, so a swab taken within a day of contact can be negative in someone who later tests positive. Without symptoms, waiting a few days after the exposure gives a more meaningful answer; if symptoms appear sooner, test then.

PCR can keep finding fragments of viral genetic material for weeks after recovery, when no intact, transmissible virus remains. A late positive in someone who has clearly improved usually reflects that rather than a fresh infection, and your doctor decides whether it changes anything.

That no SARS-CoV-2 genetic material was found in the sample you gave, at the moment you gave it. If you were swabbed very early after an exposure, or your symptoms worsen over the following days, repeat the test rather than relying on the earlier answer.

No. This is a single-target PCR that answers whether SARS-CoV-2 is present. Naming a variant needs genomic sequencing, which is a public-health laboratory activity rather than a routine clinical test, and it would not change how an ordinary infection is managed.

It is brief and uncomfortable rather than painful: the swab sits in the nostril for a few seconds and can make your eyes water. Tell the collector if you have had recent nasal surgery or frequent nosebleeds, so they can take the sample gently.

It depends on why you are testing. A documented result matters when you live or work with vulnerable people, when a clinician needs to confirm the cause before treating, or when someone requires it in writing. For mild symptoms with none of those in play, your doctor may simply advise rest and fluids.

We cannot speak for individual airlines or destinations, and their requirements change. The report is a laboratory-issued RT-PCR result naming the test performed and the sample taken: ask us whether that report format meets your airline's requirement before you book the appointment.

AED 199 covers the swab, the RT-PCR run and the physician-reviewed Smart Report, released within 24 hours of the sample reaching the laboratory. Free home collection anywhere in Dubai is included, 7 days a week, and a lab visit costs the same.
