Abstract

Background: Coronavirus has continued to ravage the world with several countries either currently experiencing a second wave of the pandemic or instituting more stringent control measures to forestall further spread. Laboratory testing plays a major role in diagnosing the disease, but the standard diagnostic test is very expensive. Several countries have reduced testing thereby jeopardizing the initial gains of case detection. There is now a need for cheaper and more readily available preliminary testing options to determine who really requires the standard testing especially in low- and middle-income countries.

Method: Serum samples from the pool of asymptomatic participants for COVID-19 testing were obtained. They were divided into two groups which included those who tested positive and those who tested negative. Levels of serum Immunoglobulin M was measured in those samples using ELISA techniques and the values were compared between the two groups to determine if there was a difference.

Result: A total of 83 samples were evaluated for this study. 44 of them were obtained from the COVID-19 positive pool while the remaining 39 were from the COVID-19 negative pool. There was no statistical difference in the age group, gender and occupation between the two groups. The mean (± SD) of serum Immunoglobulin M was 4.11 (± 3.70) µg/ml from the COVID-19 positive pool and 4.53 (± 3.49) µg/ml from the COVID-19 negative pool; there was no statistical difference between the two groups.

Conclusion: This study found no difference in the values of serum Immunoglobulin M between COVID-19 positive sample pool and COVID-19 negative sample pool. This calls for a continued search for other alternative cheaper testing platforms for COVID-19 especially in low- and middle-income countries.
