Intermediate magnification micrograph of moderate<unk> . H&E stain. Acute choriodeciduitis, with neutrophils seen in the chorion and decidua. H&E stain. Pathologic<unk>  is diagnosed from a histologic (tissue) examination of the fetal membranes. Confirmed histologic<unk>  without any clinical symptoms is termed subclinical<unk>  and is more common than symptomatic clinical<unk> . Infiltration of the chorionic plate by neutrophils is diagnostic of (mild)<unk> . More severe<unk>  involves subamniotic tissue and may have fetal membrane necrosis and/or abscess formation. Severe<unk>  may be accompanied by vasculitis of the umbilical blood vessels due to the fetus' inflammatory cells. If very severe, funisitis, inflammation of the umbilical cord connective tissue, occurs. Suspected clinical diagnosis The presence of fever between 38.0°C and 39.0°C alone is insufficient to indicate<unk>  and is termed isolated maternal fever. Isolated maternal fever may not have an infectious cause and does not required antibiotic treatment. When intrapartum (during delivery) fever is higher than 39.0°C, suspected diagnosis of<unk>  can be made. Alternatively, if intrapartum fever is between 38.0°C and 39.0°C, an additional risk factor must be present to make a presumptive diagnosis of<unk> . Additional risk factors include: * Fetal tachycardia * Maternal leukocytosis (>15,000 cells/mm³) * Purulent cervical drainage Confirmed diagnosis Diagnosis is typically not confirmed until after delivery. However, people with confirmed diagnosis and suspected diagnosis have the same post-delivery treatment regardless of diagnostic status. Diagnosis can be confirmed histologically or through amniotic fluid tests such as gram staining, glucose levels, or other culture results consistent with infection.
