Abstract
Serum HCG-β has been assayed in 100 cases of ectopic pregnancy. Results above 10 IU/I were considered positive. Positive values were found in 97 cases, of which 23 were within the range of a normal pregnancy, one was above and 73 below the normal range.
In the 3 cases with a negative HCG-β value, devitalized ectopic pregnancies were found at operation.
The routine urine pregnancy test was negative in 53, positive in 29 and not performed in 18 cases.
