Frequently Asked Questions

What is a laboratory PCR test?

Polymerase Chain Reaction (PCR) or Nucleic Acid Amplification Test (NAAT): This type of test, also called molecular or viral test, is performed by swabbing the nose or mouth. The test detects some of the genetic material of the virus. It is currently considered the best test to determine if a person has recently been infected with the virus.

What is a PANBIO rapid test?

Antigen testing: These tests are performed by nose swabbing. Instead of detecting the genetic material of the virus, they detect a protein that is present in it. They are usually available as “rapid” tests that can be performed in a physician’s office. The speed with which the results are obtained makes these tests very useful.

What is the difference between a Lab PCR test and a PANBIO rapid test?

A PCR test is much more sensitive, allowing the detection of virus with lower viral loads than antigen tests. Therefore, if you may have been exposed to or near a person who tested positive, we recommend performing a PCR test.
If, on the other hand, you just want the peace of mind of knowing that you don’t have the active virus, or if you are doing a quick high-spectrum surveillance program, you can do it with a rapid test.

What is the difference between Panbio rapid tests and serological or antibody tests?

Serological or antibody tests are performed using a blood sample and detect the antibodies that the body produces to fight the virus. These tests are best suited to determine if the person was exposed to the virus in the past, but are NOT recommended to indicate if the person is currently infected. 
Therefore, MedLife does NOT provide rapid serological or antibody tests.

What certifications does your laboratory have for conducting the study?

We are recognized by the InDRE (Institute of Diagnostic and Reference Epidemiology) which is the regulatory body of the Mexican Ministry of Health supporting the results. That is in addition to a notice of operation from COFEPRIS (Federal Commission for Protection against Health Risks)

Where will we perform the test?

In the comfort of your home or office, under the strictest conditions of hygiene.

Should I fast or prepare for the study?

The following requirements have to be met when performing the study:

  • Not having eaten food and/or chewing gum for at least two hours before the sample is taken.
  • Not having done any nasal cleansing at least two hours before the sample is taken.
  • If you are taking antiviral or antibiotic medication, it is important to mention the name of the medication.

What is the turnaround time for the tests?

The response time for the Covid-19 test is 24 hours.

What do I do after the sample is taken?

Once the sample is taken, you may continue with your normal life. This test does not require any rest or additional treatment.

Can I take the test without an appointment?

Appointments are necessary, as the tests available for COVID-19 are very limited. If the person will be in the house at the same time as another appointment is happening, there may be an exception to this rule by scheduling the appointment minutes before the technician arrives.

What prevention measures will be taken at the time of the test?

Only the person performing the study will go in the house. We may make exceptions for a family member to accompany minor patients, people with disabilities or those requiring assistance.

Where can I see my results?

On our website, you can go to the results section and enter the user and date of birth and the system will send you the results by mail as soon as they are available.

How is the COVID19 detection sample taken?

It is done by sampling a nasopharyngeal exudate and a pharyngeal exudate.

  • Nasopharyngeal exudate: it is taken through a nostril, where a swab is gently introduced, until it reaches the nasopharyngeal region, where it is rotated in order to obtain material to study the cells infected by the virus.
  • Pharyngeal Exudate: it is taken by lowering the patient’s tongue with a tongue scraper and gently inserting a swab into the back wall of the throat (oropharynx) to obtain a sample of cells infected by the virus.

The sampling process takes approximately 5 minutes.

How is the study conducted, what method is used?

After taking the sample, it is analyzed with PCR technique or the PANBIO technique, where the detection of genetic material of the virus is made and the progression of the virus reproduction is monitored.
In order to carry out these studies, trained personnel are required and have the accreditation and support of InDRE and COFEPRIS.

How long does it take to get the test results?

Tests in Mexico City taken before 10am are delivered the same day at 10PM, tests taken between 10am and 9pm (our last appointment) are delivered the next day at 6PM
For the rest of the country, results are delivered the next day at 10PM

What should I do if I have COVID-19 symptoms?

If you suspect that you have been exposed to this disease and have any of the symptoms listed as fever, dry cough or severe fatigue, it is highly recommended that you confirm the presence of the virus in your body through laboratory studies.

What do I do if the COVID-19 test is positive?

Watch your symptoms closely, if you detect: breathing difficulty, fever and dry cough, go immediately to the emergency room. It is recommended to visit the following link:

Where you can check the availability of hospitals near you. If your symptoms are not serious it is important that you keep yourself in isolation and these are the phone numbers and contact information from the Mexican Government Ministry of Health, so you can get more details:

Direct line COVID 19:
Mexico City: 555 658 1111 or send an SMS with the word covid19 to 51515
State of Mexico: 800 900 3200

Our laboratory may notify InDRE of your result, so they can perform the appropriate follow-up and epidemiological surveillance.

What is Coronavirus?

They are a very large family of RNA viruses with a characteristic crown-like appearance when observed under an electronic microscope, which gave them that name. Research indicates that they can cause diseases in animals and humans, with their primary target being the cells of the respiratory tract, this causes respiratory infections ranging from a cold to severe diseases such as SARS (Severe Acute Respiratory Syndrome). COVID-19 is a recently discovered variation of this virus.

What are the symptoms of this disease?

There are three main symptoms:

  • Fever
  • Dry cough
  • Severe fatigue.

Other symptoms that may be experienced are:

  • Sore throat.
  • Diarrhea.
  • Loss of the sense of smell and taste
  • Among others.

Usually the symptoms appear gradually or there may be asymptomatic people, which means that they do not have symptoms, but they may still be infected with the virus.
Studies indicate that 1 in 6 people will develop a serious illness with respiratory distress.

What should I submit when I take my test?

Upon arrival, the laboratory technician will ask you for your appointment confirmation, which includes:

  • Your appointment confirmation number
  • Amount to be paid or, if applicable, your payment confirmation number
  • Official ID.
  • If you wish to pay at the time of your appointment, you can pay by credit card, debit card and cash.
