Comment
Heterophilic antibodies may cause interference. 
Serum hCG increases with age in nonpregnant women. A cutoff of 14.0 IU/L should be used when interpreting hCG results in women >55 yrs. Pregnancy is unlikely in perimenopausal women 41-55 yrs with an hCG between 5.0 and 14.0 IU/L if serum FSH is >20.0IU/L.  
During pregnancy, hCG increases exponentially for 8-10 weeks after conception and begins falling at approximately 12 weeks. Week-to-week hCG levels during pregnancy show significant overlap and are not a reliable means of determining gestational age.
