E. coli testing methods include plate counting method, immunomagnetic bead method and automated instrument detection method.
1. Plate counting method: also called dilution plate method, is to dilute the sample first, and then suck the diluted sample in a certain environmental conditions to culture until it grows into colonies, according to the dilution and the number of samples to calculate the number of E. coli.
2. Immunomagnetic bead method: Immunomagnetic bead method is a kind of method to use magnetic beads as the carrier and antibody, and then separate E. coli through magnetic technology.
3. Automated Instrumental Detection Method: It is mainly detected by an automated immunoassay analyzer.
Patients who have other questions about E. coli testing methods can go to the laboratory of regular hospitals for detailed consultation.
