Laboratory Medicine

Baptist Health System Department of Laboratory Medicine is committed to providing customer-oriented, quality service. We are dedicated to providing accurate and timely laboratory information to promote recovery and maintain good health for our patients through innovation, resource management and regulatory compliance.
In order to assure the safety of our patients while providing diagnostic testing, the following elements are required:

Specimens should be collected following the guidelines of the BHS Laboratory Directory of Service. In the event that submitted specimens are unacceptable for testing (e.g. gross hemolysis, mislabeled sample), the referring entity will be notified and when appropriate, a recollected sample will be requested. In the event that the sample is irretrievable (i.e. CSF), a written request from the physician ordering that testing be performed on the suboptimal specimen will be required. 

For explicit instructions concerning collection of Blood, Microbiology and Pathology specimen submission refer to the sites below.
