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
