Results
In our study PT, aPTT, D-dimer, INR, PLT levels of a total of 238
individuals who were admitted to our hospital with a suspicion of
COVID-19 were examined and evaluated according to their COVID-19
results. Half of these 238 individuals were individuals with a negative
COVID-19 test result and the other half were patients with a positive
COVID19 test result. The descriptive information of the study is given
in table 1.
The test reference range of the samples analysed in Biochemistry
Laboratory was taken as 10-14 seconds (sec) for prothrombin time (PT).
While 11.46±0.86 sec. PT mean value was found in PCR negative
individuals, 12.97±3.65 sec was found in PCR positive patients. When PT
values were examined, a significant difference was found between both
groups and the difference was found as statistically significant
(p<0.001), (Table 2).
The test reference range of the samples analysed in Biochemistry
Laboratory was taken as 18-36 seconds (sec) for activated partial
thromboplastin (aPTT). While 24.38±3.40 sec. aPTT mean value was found
in PCR negative individuals, 24.18±4.83 sec was found in PCR positive
patients. No significant difference was found between the two groups
(Table 2).The test reference range of the samples analysed in
Biochemistry Laboratory was taken as 0-0.5 µg/ml for D-dimer. While
0.23±0.12 µg/ml D-dimer mean value was found in PCR negative
individuals, 2.10±5.60 µg/ml was found in PCR positive patients. When
D-dimer values were examined, a significant difference was found between
both groups and the difference was found as statistically significant
(p<0.001), (Table 2).The test reference range of the samples
analysed in Biochemistry Laboratory was taken as 0.8-1.2 for
International Normalized Ratio (INR). While 0.99±0.12 INR mean value was
found in PCR negative individuals, 1.14±0.35 was found in PCR positive
patients. When INR values were examined, a significant difference was
found between both groups and the difference was found as statistically
significant (p<0.001), (Table 2).The test reference range of
the samples analysed in Biochemistry Laboratory was taken as
142-424*109/L for platelet (PLT). While
266.75±71.36*109/L PLT mean value was found in PCR
negative individuals, 241.18±96.64*109/L was found in
PCR positive patients. When PLT values were examined, a significant
difference was found between both groups and the difference was found as
statistically significant (p=0.002), (Table 2). In addition, the
evaluation by gender for all parameters is given in table 2.
