Abstract:

Objective To analyze the effect of early detection of D-dimer on the diagnosis of deep venous thrombosis (DVT). Method 52 patients with DVT (DVT group) and 52 healthy subjects (healthy group) admitted to Jiaozhou Hospital of Dongfang Hospital Affiliated to Tongji University from May 2020 to December 2021 were analyzed. D-dimer detection was performed in both groups, and the results of D-dimer detection were observed and compared between the two groups. Result The level of D-dimer in DVT group was significantly higher than that in healthy group (P ＜ 0.05); in the DVT group, 52 cases were positive for D-dimer, and in the healthy group, 15 cases were positive for D-dimer. The sensitivity and specificity of D-dimer were 98.08% and 100.00%. Conclusion The detection of D-dimer has high sensitivity and specificity, and can effectively predict the early formation of DVT.
