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 coronavirus 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 test 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.
