A test conducted to determine pregnancy status following an assisted reproductive technology procedure, specifically after the introduction of an embryo into the uterus, yielding a negative result less than one week following the procedure. Such an early indication is generally considered preliminary and may not accurately reflect the final outcome due to the ongoing developmental processes.
Early assessment, though potentially inconclusive, offers initial information. However, it is generally considered premature due to low levels of detectable pregnancy hormones in the maternal system. A definitive determination requires a later test, typically around 14 days post-transfer, to allow sufficient time for hormone production if implantation has been successful.
