title: Cross-reaction of human chorionic gonadotrophin in Immulite 2000 luteinizing hormone assay.
abstract: METHODS
  The cross-reactivity of human chorionic gonadotrophin (hCG) in the new DPC Immulite 2000 luteinizing hormone immunoassay was studied using sera from healthy pregnant women and pooled serum spiked with hCG standard IRP 75/537.
  
  
  CONCLUSIONS
  Significant positive bias was seen in sera from pregnant women and in IRP 75/537 spiked serum.
