In the diagnosis of DHF, APTT + normal PT + PC < 100 × 109 cells/L, PC < 100 × 109 cells/L + ALT > 40 U/L, PC < 100 × 109 cells/L + ALT > 40 U/L + AST > 40 U/L, prolonged APTT + normal PT + AST > 40 U/L, and prolonged APTT + normal PT + ALT > 40 U/L were found to have a comparable sensitivity and specificity in the diagnosis of DHF. Here, GPT is linked to Dengue hemorrhagic fever.
