A positive pregnancy test, but with levels of pregnancy hormone too low for ultrasound documentation of a pregnancy.
Biochemical evidence of a possible developing pregnancy based on a positive blood or urine pregnancy test; at this point, pregnancy is presumptive until confirmed by ultrasound (see also clinical pregnancy).
An apparent, but not real, pregnancy. The hCG level in the blood rises high enough to yield a positive pregnancy test, but then stops rising and does not lead to a clinical pregnancy.
A positive pregnancy test ( elevated hCG level in the blood or urine) before pregnancy can be verified by ultrasound. Often used to refer to a pregnancy that has failed before reaching a size large enough to be seen on sonogram.
a condition when a women tests positive for pregnancy tests but shows no other signs or symptoms of pregnancy
a miscarriage, except that you can only diagnose it by a urine or blood test
an early miscarriage that occurs at around the time the menstrual cycle is due
a pregnancy that produces HCG but does not develop into normal pregnancy

When the HCG level continues to rise although there is no actual pregnancy
The false appearance of pregnancy due to changes in the pregnancy hormone.
A pregnancy where hCG levels are detected, but the pregnancy is lost before a heartbeat is seen on an ultrasound. This is a very early miscarriage -- often before the woman misses a period.
form of miscarriage. It is termed "chemical" because the only clinical evidence of pregnancy is a lab test, which indicates that that implantation occurred but only developed long enough to raise your circulating blood level of hCG. These are often early non-viable genetic "accidents."
The appearance of pregnancy due to changes in hormonal levels
A positive hCG level in the blood that fails to continue to rise and does not lead to a clinical pregnancy.
Very early pregnancy that is indicated through a positive pregnancy test only. When applied to IVF, a chemical pregnancy may not be a pregnancy at all, but rather the result of the hCG injection creating a false-positive pregnancy test. This term may also refer to a true chemical pregnancy that may or may not progress to a clinical pregnancy. When comparing IVF Success Rates, “Chemical Pregnancy Rates” are not very helpful.
