GROWTH HORMONE METHOD UPDATE AND REFERENCE RANGE CHANGE

The growth hormone (GH) method used by LifeLabs has been re-standardized by the vendor to align with the preferred calibration process for this analyte using a recombinant 2nd international standard (IS) 98/574. This standard replaces the pituitary derived source from the World Health Organization (WHO), 1st IS 80/505.
Performance of the new reagent has been validated and a decrease in observed GH values of approximately 25% may be expected on patient results.

Accordingly, the reference range has been changed as follows:

  • Male                                   <0.80 µg/L >
  • Female                               <8.00 µg/L >

It is advised that baseline GH values be re-established for patients undergoing serial measurements. The reporting range of results remains unchanged.
