This cohort study suggests that laboratory levels of LDH, CRP, ALT and NEU can be useful in predicting the results of COVID-19 test.
This diagnostic accuracy study sought to determine the accuracy of laboratory parameters in predicting cases with positive RT-PCR for COVID-19. Researchers evaluated 200 cases of potential COVID-19. RT-PCR was positive in 35% cases. Patients with positive RT-PCR had significantly higher neutrophil counts, C-reactive protein, lactate dehydrogenase , aspartate aminotransferase, alanine aminotransferase, and Urea levels in serum.
Patients with positive RT-PCR also had lower white blood cell count and serum albumin levels.
