- The primary day of the LMP is counted as day 1 of the gestational age.
- The gestational age is calculated by including 7 days to the primary day of the LMP, plus the variety of accomplished weeks from the LMP date.
- The ensuing gestational age is adjusted to the closest full week.
Instance: If the primary day of the LMP is June 15, and the anticipated supply date is September 20, the gestational age is calculated as follows:
Day 1 of LMP (June 15) + 7 days = Day 22
Variety of accomplished weeks from LMP date (June 15 to September 20) = 13 weeks (91 days)
Gestational age = Day 22 + 13 weeks = 23 weeks (153 days)
Nonetheless, this system is just not the one one utilized in being pregnant calculators. Different formulation, such because the Dubowitz examination and the Ballard rating, use bodily examination and ultrasound findings to estimate gestational age.
