Laboratory Policy:  The Wyoming Public Health Laboratory, in collaboration with public health officials, reserves the right to establish criteria for the acceptance and rejection of specimens for testing.  These criteria are stated in the Manual of Laboratory Services.  For all laboratory sections, specimens must be labeled properly.  Every clinical specimen container must have the patient's name or other appropriate identification. 

All specimens must be accompanied by a properly completed laboratory test request form. Federal regulations (CLIA) require the following minimal information on clinical laboratory test requisitions: patient's name or other unique identifier; test requestor; test(s) to be performed; date of collection of specimen; specimen source and any additional information relevant and necessary to a specific test. Testing may be delayed or not performed if the required information is not submitted.

Additionally, certain tests may have very specific submission criteria.  Please call before shipping, if you have any questions.  Also, be aware of holidays and weekends when shipping, we are not staffed 24/7.

Questions regarding laboratory policy on specimen criteria may be addressed to the Laboratory Program Manager/Director or the supervisors of the section in which the laboratory tests are performed.

Laboratory Reporting: Wyoming Public Health Laboratory reports are sent only to authorized parties submitting the specimen.  Wyoming state law requires notification of health officials when reportable communicable disease organisms are isolated and identified.  Except for these situations, copies of laboratory reports will not be released to others except with the written request and permission of the original submitter.  The Chemical Testing Program has special criteria for release of reports.

Other Tests:  For tests not offered by the laboratories listed above, contact the Wyoming Public Health Laboratory. The Centers for Disease Control and Prevention, Atlanta, Georgia, will accept certain specimens for unusual diseases, but only with prior arrangement through the Wyoming Public Health Laboratory.

The Wyoming Public Health Laboratory is an integral part of disease surveillance conducted by the State Epidemiologist.   As such, we provide confirmatory or reference testing for laboratories isolating organisms or otherwise providing laboratory tests which aid in the diagnosis of reportable infectious diseases. Hospital and other private or public laboratories are requested to submit subcultures, smears, or serum specimens for reportable disease to the WPHL as an aid to the surveillance process.

Certifications:  Wyoming Public Health Laboratory holds Certificate #53D0662169, issued by the Health Care Financing Administration under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88).  We also hold a Drug Enforcement Agency (DEA) Certificate and a certificate issued by the Environmental Protection Agency (EPA) under the Safe Drinking Water Act (SDWA) Program (PL 93-523). The Wyoming Public Health Laboratory participates in appropriate proficiency testing programs administered by the College of American Pathologists (CAP), the Centers for Disease Control and Prevention (CDC), the Environmental Protection Agency (EPA), and other approved private, federal, and state proficiency testing providers.

Ordering Sample/Specimen Mailing Containers:  The Wyoming Public Health Laboratory supplies mailing containers for collection of samples/specimens which comply with all U. S. Postal Service regulations. Proper usage should practically eliminate leakage or breakage in transit.  Instructions and request forms are included with the containers.  Specimens received in unsatisfactory containers or not collected and identified properly will not be examined.

Water samples must be submitted in mailers provided by the Wyoming Public Health Laboratory. 

Payments/Prices:  The Wyoming Public Health Laboratory is partially supported by legislative appropriations from the Wyoming general fund.  We also obtain support from federal grants and appropriations.  WPHL has been mandated by the Wyoming legislature to adopt a fee for service business model.  We are phasing this billing requirement in during the years of 2013 and 2014.
