Tag: False positive pregnancy test

For those undergoing fertility treatments, the timing of an hCG trigger shot is crucial for inducing ovulation, but a common source of anxiety is how long the medication remains detectable in the system. A 2020 study highlights the wide inter-individual variability, showing that factors like body mass index (BMI) can influence how quickly the body metabolizes the hormone. This lingering presence of exogenous hCG is the reason a home pregnancy test can show a false positive, causing significant emotional distress.

The half-life of an hCG injection is typically between 29 and 48 hours, but the hormone can remain detectable in your system for up to two weeks. Knowing exactly **how long does the hCG trigger shot stay in your body?** is crucial for anyone undergoing fertility treatments to avoid misleading and confusing pregnancy test results.

Human chorionic gonadotropin (hCG) is the hormone pregnancy tests detect [1.2.2]. While pregnancy is the most common reason for its presence, it's crucial to understand **what medications increase hCG levels**, as some can lead to artificially elevated readings and false-positive results [1.3.2].

While home pregnancy tests are highly accurate, yielding a false positive is rare but possible. This can occur when certain medical conditions or medications interfere with the test, raising the crucial question: What drugs can cause a false positive pregnancy test?.
