  • checkToP® is a urinary test which indicates the outcome of the treatment after a previously confirmed Termination of intrauterine Pregnancy (ToP).1
  • checkToP® is not a classical pregnancy test. checkToP® is designed to detect urinary hCG at concentrations ≥ 1 000 mIU/mL, the appropriate sensitivity level for a MToP follow-up test.1 This makes urine testing a well suited tool for MToP follow-up.
  • checkToP® is based on the human chorionic gonadotropin (hCG) blood testing. Indeed, it has been shown that measuring serum ß-hCG is as effective as ultrasound to confirm a successful medically induced abortion in early pregnancy (n=133).2 Moreover, the concentration of hCG and ß-hCG in urine are similar to or slightly higher than those of serum.3 Tests with detection limits of 1 000 mIU hCG/mL or higher are usually negative 2 weeks following complete induced abortion.4
  • ß-hCG levels drop rapidly under 1 000 IU/L after abortion.5


checkToP® is a complementary method to check medical abortion and do not replace the mandatory follow-up visit.


It has to be performed 14 days after the first MToP drug intake1

checkToP® must be performed on the first morning urine that should be more concentrated1

As simple as a pregnancy test


Hold the absorbant tip directly in
your urine stream or collect your urine 
in a clean and dry container and
dip the absorbent tip into the urine for
at least 5 to 10 seconds.
Take care no urine enters
in the test window


Lay the test device on a dry flat surface with the two windows facing up1


Wait between 5 to 10 minutes
to read the test results1


Do not read before 5 minutes
or after 10 minutes1
