Abstract
Objective
To determine if the same systematic alteration of serum values seen for alpha-fetoprotein (AFP) in diabetic patients is also seen for β-hCG and unconjugated estriol (uE3).
Methods
Serum AFP, β-hCG, and uE3 results were obtained in 18,639 patients for whom complete follow-up information was obtained. Patients were divided into euglycemic (n = 18,088), insulin-requiring diabetics (n = 104), and non-insulin-requiring diabetics (n = 437), as well as by race.
Results
The 20% adjustment used for AFP appropriately corrects serum values. No such systematic variation is seen for either β-hCG or uE3 by glycemic status or race.
Conclusion
No adjustment for β-hCG or uE3 is necessary for diabetes for biochemical screening programs.
