Microbiology Specimen Submission

Specimens for screening of enteric bacterial pathogens, parasites, and mycobacterium can be sent to the laboratory by using collections kits provided by the laboratory. Specimen kits can be ordered by mailing or faxing an order form to the customer service unit at the laboratory. Click here for the order form.

For all human specimens submitted for microbiology testing, see the Microbiology Specimen Submission Guidelines for specific collection, rejection, and transport guidelines.

Please use the Fax Authorization Request Form for all re-issued reports, demographic corrections, test additions, or other laboratory report modifications. The form must be signed, dated and faxed to the Kansas Health and Environmental Laboratories (KHEL) before any final changes will be made on all preliminary or final laboratory reports.

Packaging and Shipping Instructions


Provide laboratory support to local health departments, clinics, hospitals, physicians, and units of Kansas government for the detection and identification of infectious bacterial diseases and parasites. These services assist in the medical treatment of Kansas residents and provide the state public health programs with disease incidence information to guide prevention and intervention efforts to reduce the transmission of infectious diseases within the state.

Analytical Services provided by Microbiology include stool culture for the detection of Salmonella, Shigella, Campylobacter, and Shiga toxin-producing E. coli (STEC), including E. coli O157:H7.  Vibrio cholerae and Yersinia enterocolitica testing is also available upon request. Gonorrhea identification is provided for culture isolates that were isolated from body sites for which the nucleic acid testing methods normally used are not approved. Laboratory testing for M. tuberculosis and other mycobacteria is provided to all health care providers in the state and includes identification of all mycobacteria and antibiotic susceptibility testing for M. tuberculosis. Parasitology testing is performed for all intestinal parasites. Specimens for blood borne parasites such as malaria are sent to the Centers for Disease Control and Prevention for analysis. In addition we utilize DNA fingerprinting by Pulse Field Gel Electrophoresis (PFGE) to further characterize enteric bacteria associated with foodborne outbreaks.

We are now offering polymerase chain reaction (PCR) for the detection of Bordetella pertussis in nasopharyngeal specimens. This is a sensitive test procedure and will reduce both the false positive and negative results associated with the direct fluorescent antibody (DFA) test that we have been using.
