Free and Total Testosterone for Female/Child Test Updates
July 18, 2014
 

Effective immediately, CHI Health Laboratory test requirements for Free and Total Testosterone for Females and Children require a Red Top Serum Tube as the only acceptable container type due to new methodology. Internal investigations at Pathology Associates Medical Laboratories, our Reference Lab, have indicated that use of SST tubes (Gold tops) may result in falsely elevated values. The online lab directory has been updated to reflect this change. 


Vitamin B1 Plasma versus Vitamin B1 Whole Blood -- Clarification
July 18, 2014

Due to the recent influx of issues with ordering and collection of Vitamin B1 (Thiamine), CHI Health Laboratory (ACL) is providing the following clarification between Vitamin B1 Plasma and Vitamin B1 Whole Blood. These specimens are not interchangeable.

 For the Vitamin B1 Plasma:

  • Used to monitor recent intake of Thiamine
  • EPIC Lab Order Summary will say "Vitamin B1".  The Cerner barcode label will say "VitB1PL". 
  • Collect - Green sodium / lithium heparin tube or Lavender EDTA.
  • Centrifuge and transfer plasma to an amber transport tube. The plasma must be protected from light.  The specimen will be rejected if it is not protected from light.
  • Write “Plasma” on the aliquot tube.
  • Send to Reference Lab frozen, as it is a critical frozen test.

 For Vitamin B1 Whole Blood:

  • Used to determine Thiamine deficiency
  • EPIC Lab Order Summary will say "Vitamin B1, whole blood".  The Cerner barcode label will say "VitB1WB".
  • Collect - Lavender EDTA or Green sodium / lithium heparin and protect tube from light
  • Do NOT centrifuge.  Transfer whole blood to an amber transport tube.  This specimen must be protected from light. It will be rejected if not protected from light.
  • Write “Whole Blood” on the aliquot tube.
  • Send to Reference Lab frozen, as it is a critical frozen test.

Please share this information with the appropriate staff.  



Reference Lab Changing to PAML

Beta hCG Tumor Marker Testing 
June 16, 2014

Beta hCG tumor markers will be performed at PAML so providers who would like to re-baseline their patients may do so. Re-baselining would be performed by evaluating two samples collected together to reestablish a baseline on two data points with the new methodology. In order to facilitate the re-baselining transition, a second tumor marker assay will be performed by the new method at no charge, Please contact Customer Service at 402-717-5227 to obtain the proper form to fill out and return with patient specimens. All re-baselining needs to be completed by October 1. 2014.
