Challenges in Test for Coronavirus

The Corona virus pandemic has resulted in situations where by clinical laboratory and testing for SARS-CoV-2 amidst worldwide discussions on how to end it. Clinical Laboratories have in turn came out with ways to develop, validate and implement a series of molecular and serological assays to test for the presence of Coronavirus. Through immense research conducted globally, laboratory clinics have made it easier to identify cases, making informed decisions on isolation and ways to reduce the spread of the virus. Due to increased cases, the demand for testing has increased immensely. With the increase in demand came challenges. Below are some of the challenges faced in the rapid antigen test.

The first challenge in the testing of coronavirus is in an adequate supply of test reagents. Due to the immense increase in several cases and people to be tested, clinical laboratories are forced to do more with less time. In some places where the issue is rampant, the pooling strategy is advised. This is where samples from different individuals maybe 3, 5, or 10 people are combined and tested as one. Where the resulting test negative all individuals are taken to be negative. In cases where the results become positive then the individual test is retaken. In this case it makes the whole process even longer.

The second challenge in the rapid antigen test for travel for coronavirus is in the accuracy of the results. Due to the increased demand for the tests, clinical laboratories are using different tests to detect COVID19. For instance, in cases where air swabs as a method of collecting samples are used, there is a likelihood of a positive individual to test negative due to lack of, nucleic acid materials in the sample.

The last challenge is difficulties in obtaining a sample from individuals. As we know the commonly used methods of obtaining samples can be very uncomfortable for many. A nose and throat swab for an exam makes many people flinch. This poses a challenge especially when you have several other people waiting.

Shortcomings Of PCR Swab Test

PCR test is the most common test that is frequently used to detect coronavirus worldwide due to its efficiency. It determines the presence of an active COVID 19 infection. A PCR test can be done on any fluid but the virus mostly resides in the nasal pharyngeal area hence most of the samples taken are obtained from this area. This process takes a minimum of 10 seconds. Despite its effectiveness, a PCR swab test has its shortcomings. Below are some of the shortcomings involved.

The first shortcoming of the rapid antigen test is the discomfort while taking the swab sample. The swab sample is supposed to be obtained from the area where the sinuses meet the throat. This process tends to be very uncomfortable, some people even term it painful. This can be a challenge, especially to those tested. In some areas, people evade going for tests due to fear of the PCR swab test.

The second shortcoming of the PCR swab test is the false-negative results in some cases.  The percentage of molecular tests that give, false negatives have increased from 2% to 37%. This mostly happens when a test is conducted in the earliest stages of the infection.

The third shortcoming in the rapid antigen test for travel is that it takes a while to obtain results. Time is what most people don’t have. In cases where the victim is aged and the immune system not too strong, time is not something they afford. The time is taken to wait for the result can result in serious issues that could have prevented otherwise. We have cases where a PCR swab test yields result after one to two weeks.

The last shortcoming of a PCR swab test is that it cannot detect the history of the virus in someone who has since recovered.

How A Fit To Fly Covid Test Near Me Works

Covid-19 fit to fly test is one of the many policies that countries took to cut the chain of transmission of the coronavirus as a result of interactions with people from the most affected countries. As such, one is required to produce a negative Covid-19 swab test and certificate to show that he or she is currently not infected with the coronavirus. On failure to provide proof and confirmation of the same, he or she cannot be allowed to board a passenger plane.  A fit to fly covid test near me usually works as discussed below.

There are usually two types of the fit to fly covid test near me. The first type is the new priority service testing. In this type of testing, one is guaranteed to receive his or her results within a day after his or her samples are received at the laboratory. This is mostly used by persons who need to travel urgently. A case example is a patient who needs urgent treatment or urgent surgery. The last type of fit to fly covid testing is the standard service testing. In this type of testing, one is set to receive his or her results 28 hours after his or her samples have been received at the lab. As such, this testing is only useful for individuals who do not need to travel urgently.

In more developed countries, this testing usually works by an interested person requesting a  testing kit. The test kit includes all the equipment which will ensure the samples of the person in question are taken correctly and other equipment such as tracked postage-paid envelop. Once the person samples have been analyzed he or she will be emailed by the health agency to notify on the results of the testing and if negative a pathology report of the results alongside fit to fly covid certificate will also be emailed.

The testing usually incorporates the use of PCR swab test which is as accurate as up to 99.9%. This is because the test shows if one has been affected by the coronavirus even in cases where the subject is asymptomatic.
