Diagnostic value of the matrix metalloproteinase-8 rapid test for detecting microbial invasion of the amniotic cavity.
The purpose of this paper was to compare the MMP-8 PTD Check (MPC) test with other indirect tests for detecting microbial invasion of the amniotic cavity (MIAC). Amniotic fluid (AF) was analyzed in 155 women for white blood cell (WBC) count, glucose concentration, and an MPC test and evaluated for MIAC using cultures for aerobic/anaerobic bacteria and mycoplasmas and polymerase chain reaction (PCR) of chlamydia. The median AF glucose concentration was lower and the median AF WBC count was higher in women with MIAC than in women without MIAC (p < 0.01 and p < 0.001, respectively). Also, the positive rate of the MPC test was higher in women with MIAC than in women without MIAC (p < 0.001). The sensitivities of AF glucose concentration, AF WBC count, and the MPC test for the detection of MIAC were 58.6%, 75.9%, and 86.2%, respectively. The specificities for the detection of MIAC were 76.2%, 80.2%, and 74.6%, respectively. We conclude that the MPC test is a rapid, easily performed, and accurate indirect method for detecting MIAC.
