The Relationship between COVID-19 suspected patient’s coagulation and platelet parameters and Polymerase Chain Reaction Results

Abstract

Objective: This study aims to investigate the relationship between prothrombin time (PT), activated partial thromboplastin time (aPTT), INR (International Normalized Ratio), and D-dimer levels, platelet (PLT) levels at hospital admission, and positivity or negativity of Polymerase Chain Reaction (PCR) test results in patients with suspected coronavirus disease-19 (COVID-19) followed at COVID-19 services. Methods: This study was performed on 238 patients with the prediagnosis of COVID-19, all patients are hospitalised in Samsun city at our hospital between 11 March 2020-30 May 2020. According to COVID-19 PCR test results, PCR test negative 119 individua and PCR test positive 119 patients were included in the study. PT, aPTT, D-dimer, INR, and PLT levels were examined. Results: While PCR test negative individuals had a mean PT value of 11.46 +/- 0.86 sec, PCR test positive patients had a mean PT value of 12.97 +/- 3.65 sec (p<0.001). There was no significant difference in mean aPTT values of PCR test positive and negative patients. Whereas INR, D-dimer increased significantly in PCR test positive patients. PLT value decreased from a mean value of 266.75 +/- 71.36*10(9)/L in PCR test negative patients to 241.18 +/- 96.64*10(9)/L in PCR test positive patients (p=0.002). Conclusions: In our study, it was found that in patients who were admitted to hospital with COVID-19 suspicion and followed up in COVID-19 services, PT, D-dimer, INR, PLT values were important in detecting coagulopathy and thrombocytopenia in the group who were PCR positivity.
