AMH Assay Change

On 5th May 2015 the method for anti-mullerian hormone (AMH) changed from a manual ELISA method (Beckman AMH Gen 2) to an automated immunoassay (Roche). This enables a faster turn-around time of 3 days to be achieved for this test.

Method comparison has shown that results for AMH have a proportional 20% decrease compared to the previous assay.

New reference ranges are as follows:
Adult males: 10.2 – 82.8 pmol/L

Adult females:
