Patients with suspected or confirmed ectopic pregnancy who exhibit signs and symptoms of ruptured ectopic pregnancy should be emergently transferred for surgical intervention. This occurs when a fertilized egg implants in a location that can't support its growth. A combination of -hCG level greater than the discriminatory level and ultrasonography that does not show an intrauterine pregnancy should raise concern for early pregnancy loss or an ectopic pregnancy.5 The discriminatory zone was previously defined as a -hCG level of 1,000 to 2,000 mIU per mL (1,000 to 2,000 IU per L); however, this cutoff can miss some intrauterine pregnancies that do not become apparent until a slightly higher -hCG level is achieved. 1.

In this case, the pregnancy is called a pregnancy of unknown location. There is no consensus about the next steps if a pregnancy is of unknown location. Patients should be counseled to avoid taking folic acid supplements and nonsteroidal anti-inflammatory drugs, which can decrease the effectiveness of methotrexate, and to avoid anything that may mask the symptoms of ruptured ectopic pregnancy (e.g., narcotic analgesics, alcohol) and activities that increase the risk of rupture (e.g., vaginal intercourse, vigorous exercise). A single-dose methotrexate protocol is recommended for medical management of patients with ectopic pregnancy and low initial -hCG levels. Author disclosure: No relevant financial affiliations.

In a viable intrauterine pregnancy with an initial -hCG level less than 1,500 mIU per mL (1,500 IU per L), there is a 99% chance that the -hCG level will increase by at least 49% over 48 hours.15 As the initial -hCG level increases, the rate of increase over 48 hours slows, with an increase of at least 40% expected for an initial -hCG level of 1,500 to 3,000 mIU per mL (1,500 to 3,000 IU per L) and 33% for an initial -hCG level greater than 3,000 mIU per mL.15 A slower-than-expected rate of increase or a decrease in -hCG levels suggests early pregnancy loss or ectopic pregnancy.

Ruptured ectopic pregnancy is associated with peritoneal signs and requires emergency surgery, although most patients present with bleeding or pain before rupture.39, Surgical treatment options include salpingectomy or salpingostomy, which are appropriate if the location of the pregnancy is the fallopian tube, but not if there is a less common location. Ultrasonography showing neither intrauterine nor ectopic pregnancy in a patient with a positive pregnancy test is referred to as a pregnancy of unknown location. Human chorionic gonadotropin (hCG) is a glycoprotein hormone composed of 2 dissimilar subunits, alpha and beta, joined non-covalently. The rate of increase slows as pregnancy progresses and typically plateaus around 100,000 mIU per mL (100,000 IU per L) at 10 weeks' gestation.16 A decrease in -hCG of at least 21% over 48 hours suggests a likely failed intrauterine pregnancy, whereas a smaller decrease should raise concern for ectopic pregnancy.17, The discriminatory level is the -hCG level above which an intrauterine pregnancy is expected to be seen on transvaginal ultrasonography; it varies with the type of ultrasound machine used, the sonographer, and the number of gestations.
