•The rate of change in serum hCG levels from two consecutive visits was determined and compared to a minimal rise of 35% in 2 days (99% CI for the rise in hCG in an IUP), ...

The change in serum hCG over time (hCG ratio) and progesterone levels can be used to predict failing PULs. Mathematical models to predict PUL outcome have been developed but need to be tested in ...

Serum hCG: Positive result is defined as hCG>5 IU/L 2 weeks after ET.35 At the same time, the serum hCG level should be at least 25 IU/L at 14 days after ET36 and if continuous monitoring shows that ...

If the serum hCG level is positive, transvaginal ultrasound will be performed 2 weeks later to determine the pregnancy location and confirm foetal viability. Subsequent management will be the same as ...

An hCG level greater than 25 mIU/mL is enough to confirm a pregnancy with most at-home urine pregnancy tests. People who aren't pregnant typically have blood hCG levels less than 5 mIU/mL.

The trial is designed with a two-stage Simon design, with the possibility of early termination for futility (5% one-sided alpha level, 80% power). The treatment will be considered interesting if the ...

LH can cross-react with some assays for hCG. Administration of supplemental testosterone reduces the release of gonadotropin-releasing hormone and consequently suppresses pituitary production of LH ...

Low blood sodium, or hyponatremia, occurs when water and sodium are out of balance in your body. It can cause weakness, headache, nausea, and muscle cramps.

Normal levels of ammonia in the body depend on a person’s age and sex and range from around 100 µmol/L in infants to 16 µmol/L adults assigned male at birth.
