I’m not sure if there were any replies, but it is possible that the hCG is a postmenopausal increase in pituitary hCG. See

Diagnostic Considerations in the Measurement of Human Chorionic Gonadotropin in Aging Women,  Jennifer A. Snyder, et al., Clin Chem 2005;51(10):1830-5. -Jim

 

 

We have a 46 female who have a hCG bteween 12 and 15 UI/L since at least one year.  The results are similar after dilution and/or centrifugation at high speed.  We report as negative value < 5 and positive > 25.   Also we had the same values using a different method.

Any ideas why the values are consistently in gray zone?  Is interference still a possibility?

Thanks
