How long do hCG injections stay in your system?
Typically, it takes about 10 days for the drug hCG to clear from blood and urine. So, if you do an UPT too soon — 10 days or less after the hCG injection — you may get a false positive because you are detecting the medication that is still in your blood and urine, not the hCG that a pregnancy is making.
Does initial hCG level matter?
Look for rising numbers, not low ones. A low initial HCG level doesn’t mean it’s all over. Fertility patients, in the unique position of knowing exactly when conception occurred, are the main worriers. They test early, so a low score is likely. But what matters is how HCG levels rise.
What hCG level do you see a fetal pole?

The lowest (“threshold”) β-hCG levels associated with visible pregnancy-related structures were 390 mIU/ml (gestational sac), 1094 mIU/ml (yolk sac), and 1394 mIU/ml (fetal pole).
