Dear DSHS Laboratory Submitter:

As a follow up to the telephone call placed to your facility on April 25, 2011, this letter is intended to clarify specimen acceptance criteria for glucose, cholesterol, lipid profile, RPR, HIV and Hep C testing. A recent communication from Becton Dickinson (BD) has indicated that we can no longer accept specimens collected in serum separator tubes (SST) that have been frozen for glucose, cholesterol, lipid profile, RPR, HIV and Hep C testing. This communication describes how freezing of these specimens can compromise the accuracy of test results.

Effective May 9, 2011, the DSHS Laboratory will no longer accept serum specimens that have been collected in serum separator tubes (SST) and frozen. Specimens that have been submitted in serum separator tubes (SST) which have been frozen will be rejected as unsatisfactory for testing.

Serum specimens for glucose, cholesterol, lipid profile, RPR, HIV and Hep C may be collected in one of two ways:

  1. The specimen may be collected in a red-top blood collection tube and centrifuged within two hours of collection. The serum must then be transferred into a transport tube and frozen until shipping; or

  2. The specimen may be collected in a serum separator tube (SST), centrifuged within two hours of collection, and the serum transferred into a transport tube and frozen until shipping.

If you have any questions, please contact Susan Hoffpauir at (888) 963-7111 x 6030 or by email at Susan.Hoffpauir@dshs.state.tx.us.

Sincerely,

 

 

Susan Tanksley, PhD
Acting Director, Laboratory Services Section
