What is the coronavirus (SARS-CoV-2) PCR test (molecular test)?
It is a laboratory test that can identify the virus that causes COVID-19 (coronavirus) in
secretions from the upper throat behind the nose (nasopharyngeal exudate) and in the
throat behind the mouth (oropharyngeal). It is performed with a swab.
The medical community considers detection of coronavirus by PCR to be the gold standard.
What is the RT-PCR (molecular test) methodology?
It is a laboratory technique commonly used in molecular biology to generate a large
number of DNA copies by a process called "amplification". Exponential amplification by
reverse transcription PCR is a highly sensitive technique. That is, it can detect a very low
RNA copy number, or, in simple terms, it is effective in finding infections.
Can this molecular test detect the new SARS-CoV-2 variant?
Yes, the molecular test has been able to detect the main existing variants as of the time of
this update (April 15, 2021).
Does the molecular test identify the SARS-CoV-2 virus variant that caused the infection?
No, the molecular test will indicate whether you are infected with SARS-CoV-2, but it will
not identify the variant.
Why is it requested?
To detect if you are currently infected with the virus that causes COVID-19. If you are
infected, you will be able to receive medical care and prevent infecting others.
When is it requested?
When you think you might be infected with COVID-19, either because you have symptoms
or because you have been in contact with an infected person.
Is there an endorsement from the INS (National Institute of Health) for the performance of this molecular test by MULTILAB?
Yes, the INS, by means of the OFICIO N° 454-2020-DG.CNSP/INS, issued the "Constancia de
cumplimiento de Laboratorios Clínicos Múltiples S.A.C. - MULTILAB for molecular detection
of SARS-CoV-2 virus".
If I take this molecular test, will I be able to access the result through the State system?
Yes, our laboratory has committed to comply with the entry of the results to the Laboratory
Information Management System NETLAB of the INS, so that any patient who takes this
test will be able to access the result by entering the official website of the INS, in "covid-19
results query"
How much time should elapse since the infection for the test to detect it?
Experts suggest testing 3 to 5 days after infection may have occurred. Viral RNA is detected
before symptoms appear, peaking between the fifth and seventh day after symptom onset
and usually becoming negative within 15-30 days.
What does the test result mean?
Positive: it is highly likely that you are infected with the SARS-CoV-2 virus that causes
COVID-19. However, this test needs to be evaluated along with other tests and the results
should be interpreted by your treating physician who will evaluate them along with your
medical history, history and physical examination, and thus be able to establish an appropriate diagnosis and treatment.
Negative: the test has not detected infection, so it is likely that you are not infected. However, this test needs to be evaluated along with other tests and the results should be
interpreted by your treating physician who will evaluate them along with your medical
history, history and physical examination, and thus be able to establish an appropriate
diagnosis and treatment. If you have symptoms and the result is negative, you should
continue to monitor your symptoms and obtain information from your physician about the
need to isolate and repeat the test.
What type of sample is required?
Laboratory personnel should obtain two samples: one from the nose and one from the
mouth. The first one will be from the upper respiratory tract, by introducing a first swab
through the nasal cavity performing rotary movements making pressure on the walls of
the nostril. We will introduce a second swab through the mouth obtaining the sample from
the posterior pharynx. The laboratory personnel will place swabs in a viral transport
medium.
How accurate is the test?
The molecular test is considered highly accurate. In the case of PCR with a properly
obtained sample, the sensitivity of the test is greater than 99%. Sensitivity describes how
well a test can detect disease in infected persons.
The specificity of the test is close to 100%. Specificity describes how well a test can identify
that the disease does not exist in uninfected persons. In other words, a positive test result
means that it is highly likely that the patient is infected.
I do not have any symptoms, is it necessary to test for Coronavirus by PCR?
It is recommended to avoid spreading the infection to your family, friends and colleagues.
Research in the journal Science showed that two out of three infections of the new coronavirus have been caused by people who had not been diagnosed with the virus or had no
symptoms.
Is the test painful to perform?
Obtaining the sample should not be painful, but it is uncomfortable. Each of the two
samples takes less than 1 minute.
Are my results confidential?
Yes, Multilab will make the epidemiological report indicated in the law to the National
Institute of Health. Multilab and the National Institute of Health keep your patient's test
results confidential.
Molecular testing for travel
If you need a molecular test to travel, we offer it to you, have a safe trip.
You should know that it is not required to submit a molecular test to leave the country,
however if the country of your destination requires this test, you must do it to enter.
We recommend that you review the entry restrictions that have been established in your
destination country due to the expansion of COVID-19. You should consider that this
information may vary, so we recommend that you constantly check the official sites of the
destination country before your trip. If you have connecting flights, you should also
confirm which requirements you must meet to board and arrive at your final destination.
Technical information and test limitations:
Molecular testing by real-time PCR-RT allows qualitative detection of SARS-CoV-2 nucleic
acid (RNA), i.e. detects the virus, in lower and upper respiratory tract fluids.
No laboratory test is 100% accurate. A positive test is a strong indicator that the specimen
is from someone infected, but there is the possibility of a false positive result due to test
performance or specimen contamination issues. A negative test does not completely rule
out infection, and should not be used as the sole basis for patient management; these
results should be combined with clinical observations (fever, cough, fatigue, etc.), patient
history, and epidemiologic information.
As with all laboratory tests, the results should be interpreted in conjunction with clinical
information available to your treating physician.
If the result is negative and symptoms persist, seek guidance from your treating physician
for repeat testing or further medical evaluation.
A negative result does not at any time exclude the possibility of SARS-CoV-2 infection.
