Trigger Shot Test-Out

Estimate how much hCG remains from a trigger shot, and when it should clear below your detection threshold.

Trigger hCG remaining

78.1 IU

Still above your detection threshold of 5 IU. A positive test could be residual trigger.

Time to clear below 5 IU: ~11.0 days from injection. Half-life varies 24–36 h between people.

How is this calculated?

hCG decays by half every 24–36 hours after a trigger shot. We use exponential decay: remaining = dose × 0.5^(daysSince × 24 / halfLife). Half-life varies between people — try 24h for a fast clearance, 36h for slow. Detection thresholds: most home tests detect 5–25 IU; blood tests catch much lower.
