Abstrakt: The assessment of anti-mullerian hormone (AMH) pre- and post-gonadotoxic treatment helps define reproductive potential in young female adults facing cancer treatment. Normative childhood AMH levels are not well defined. Our objective was to help establish accurate pediatric reference intervals (RIs) for which AMH can be used to assess AMH in pediatric/adolescent survivors. Healthy female volunteers aged 6-<19 years were recruited from the Canadian Laboratory Initiative on Pediatric Reference Intervals (CALIPER) cohort. 300 serum samples were analyzed for AMH using an automated assay. Basic demographics and menstrual cycle data on the subjects were recorded at time of sample collection. Serum AMH distribution and RIs (2.5th and 97.5th percentiles) were established in four age groups. One recommended RI (0.98-7.84 ng/mL) was established for females aged 6-<19 years after outlier removal. Females 6-<9 years demonstrated significantly lower mean AMH concentration than did females 9-<12 years (Mean ± SD: 3.18 ± 1.62 and 4.16 ± 2.55 ng/mL, respectively), who in turn demonstrated significantly higher AMH concentrations than those aged 12-<15 years (Mean ± SD: 3.75 ± 1.61 ng/mL). Statistical differences are unlikely to be clinically meaningful. Menstrual status and ethnicity did not significantly impact AMH concentrations (p = 0.787 and p = 0.0965, respectively). This is the largest series of its kind using a contemporary, automated, single-batched AMH assay in a healthy pediatric female cohort. In conjunction with future data points and longitudinal data, the RI established may be a useful adjunct to reproductive health counselling delivered to pediatric cancer patients requiring fertility damaging therapies.
