STEC PCR

Justification

The STEC-PCR assay can be confirmed by the detection of a Shiga toxin-producing Escherichia coli (STEC) in the patient’s stool sample. The test looks for the presence of ST-1 and/or ST-2 genes in stool cultures. The most common cause of HUS is STEC. STEC-HUS accounts for over 90 percent of cases of HUS in children in the US and it is one of the main causes of acute kidney injury in children under the age of three years.
