COVID-19 Testing (Antibody test & PCR) in Las Vegas

Covid-19

Coronaviruses are a virus family that cause illnesses such as the common cold. In 2019, a new strain of the virus was identified, leading to a new disease that originated in China.  This virus is known as severe acute respiratory syndrome coronavirus 2 or SARS-CoV-2 or COVID-19. Unfortunately, in March 2020, the World Health Organization declared the outbreak a pandemic. 

Covid-19-Coronavirus

What are the Symptoms of COVID-19?

Symptoms of the infection usually appear 2 to 14 days after exposure to the virus. The symptoms of Coronavirus include but not limited to:

  • Fever
  • Tiredness
  • Dry cough
  • Runny nose
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Runny nose
  • Nausea or vomiting
  • Diarrhea

The following symptoms are considered emergency symptoms of COVID-19. Therefore, if you have any of the following symptoms, seek emergency medical care immediately:

  • Difficulty breathing
  • Chest pain
  • Inability to stay awake
  • Bruising of the lips and face

The severity of symptoms and infection varies from person to person. Some people experience mild signs or no symptoms at all. But others may suffer from respiratory problems, pneumonia, and even death.

It is interesting to know that some people are more at risk of experiencing severe symptoms and complications caused by COVID-19. For example, elderly people are considered high-risk groups. Besides, people with the following problems or conditions are at higher risk of experiencing severe symptoms:

  • Heart diseases such as heart failure and cardiomyopathy
  • Lung diseases such as chronic obstructive pulmonary disease, asthma, pulmonary fibrosis, and cystic fibrosis
  • Immune system disorders or weaknesses due to HIV, bone marrow transplantation, and taking certain medications
  • Pregnancy
  • Smoking
  • Type one or two diabetes
  • Obesity and overweight
  • Liver diseases
  • Kidney diseases
  • High blood pressure
  • Sickle cell disease

 

Coronavirus symptoms day by day

Usually, a viral reaction begins two to three days after the virus incubates in the body. Therefore, symptoms such as viral fever are seen in the first days of the disease. In general, the early days of infection are confusing because some people experience mild symptoms, and others may have no symptoms. The severity of the disease can usually be determined on days 5 to 10.

 

 How long does COVID-19 last?

Most people need ten days after the onset of symptoms to get out of quarantine and be with others. People with underlying disease or those with impaired immune systems may need more time.

 

How is Covid-19 transmitted?

The exact answer to this question is not clear. Unfortunately, we definitely know that the virus is currently spreading at a high rate. So far, most studies have shown that the virus is transmitted in close contact less than 6 feet (2 meters) between people by respiratory droplets during coughing, sneezing and breathing, talking, and singing.

It has also been found that the virus is spread in some conditions by small particles left in the air, which is called airborne transmission. It should be noted, however, that this is not a common way of transmitting the virus. Contact with contaminated objects or surfaces may also lead to COVID-19 transmission.

 

How to prevent

There is currently no vaccine against COVID-19 on the pharmaceutical market, although successful research is underway to find a vaccine for the disease. Therefore, according to the WHO and CDC recommendations, all people can prevent the spread of COVID-19 by the following:

  • Keep a distance of 6 feet with individuals who have symptoms of infection.
  • In general, keep a social distance between yourself and other people.
  • Wash your hands frequently, or use an alcohol-based hand sanitizer with at least 60% alcohol.
  • Use a cloth face mask in public places.
  • When coughing or sneezing, cover your mouth and nose, then wash your hands immediately with soap and water.
  • Avoid touching your eyes, nose, and mouth.
  • Disinfect high-touch surfaces regularly
  • Stay home if you are sick.

 

Hot to Know you got Infected with COVID-19?

Contact your physician immediately if you have the mentioned symptoms or you have been exposed to the virus. There are currently two tests for this infection:

  • A viral test known as PCR (Polymerase Chain Reaction) detects the current infection.
  • An antibody test that shows you have had the past infection.

Not everyone needs to do COVID-19 testing. The factors that ascertain whether you need to do a test depend on where you live.

Contact your health care provider first if you have symptoms of the COVID-19 infection and want to do the viral test. He/she will tell you if you need the test and where you can go if you do so. Remember to use a face mask before going to the testing centers.

 

How to get the COVID-19 viral test?

The lab uses a nasopharyngeal swab to collect a sample of your nose, throat, or saliva. Sampling can be a little uncomfortable. Swabbing may also be done in both nostrils to collect enough samples.

In some cases, your sputum may be sampled for testing. Early in the infection, the virus is more concentrated in the nose and throat, but five days after the onset of symptoms, more virus is found in the lower respiratory tract. Also, because the symptoms of COVID-19 are similar to the flu, your doctor may also consider testing for the flu.

 

What to do after the COVID-19 viral test?

Test results may be prepared within one hour after the test or the same day that you are tested. It may also take several days to prepare the results. COVID-19 diagnostic test results can be positive or negative:

  • If the test is positive, you should stay home and quarantine yourself to:
  • Improve your symptoms, and at least three days have passed since the last time you had a fever.
  • Pass at least ten days after the first sign appeared

If you experience severe symptoms or underlying medical conditions, your doctor may extend your isolation period. If the test is positive, but you have no symptoms, you should stay home for ten days after the test.

  • If the test is negative, it indicates that you are probably not infected with the virus. But due to the timing and quality of the test, false-negative results may occur. If the test is negative, you may get an infection in the future. Therefore, you should follow instructions such as social distancing and wearing a mask.

 

How to get the COVID-19 antibody test?

An antibody test is done on a blood sample to determine if you have had the infection before. This test determines if your body has antibodies against the virus in your body. Antibodies are proteins built by our immune system against microorganisms such as coronavirus.

 

What to do after the COVID-19 antibody test?

  • Positive results: a positive result indicates that you have antibodies against the virus in your body. But these antibodies may be built against other viruses in the coronavirus family. Another key point is that even if you have COVID-19 antibodies in your body, you may still be immune to the virus, but it is not clear how much protection the antibodies may give or how long this protection may last. The CDC has reported cases of reinfection, but remain rare.
  • Negative results: If you have not had COVID-19 before, your antibody test will probably be negative.

The body begins to make antibodies within one to three weeks after exposure to the virus. Therefore, your antibody test result may be negative because the body has not yet been able to make enough antibodies. What’s more, some patients never make antibodies against COVID-19 in their body, while others may take longer to produce antibodies.

 

Where to get a PCR test near me?

If you need to get a PCR test, you can go to your local or state health department’s website for local test information. We recommend that you contact your doctor before doing the test.
