Specimen Collection

All local public health agencies and private health care providers are eligible to submit samples.  All private health care providers must register with the State Public Health Laboratory before samples can be submitted.  Providers can register by contacting us.

The Laboratory participates in the national CLIA (Clinical Laboratory Improvement Amendments) approved proficiency testing program. Thus, all submitters must meet and follow certain criteria and procedures as established by the State Public Health Laboratory. All venous blood samples must be submitted in collection devices that are provided free of charge by the State Public Health Laboratory. Mailing supplies for the samples are also provided at no charge. These measures provide several quality assurances, including guarantees that the collection tubes do not contain detectable lead. Capillary samples must be collected in devices containing anticoagulant. Submitters may use the capillary device provided free of charge by the State Public Health Laboratory.
