What does the abbreviation G/P/A specifically quantify in a patient's obstetric history?

The abbreviation G/P/A is commonly used in obstetrics to summarize a woman's pregnancy history. It stands for Gravida, Para, and Abortus.

Gravida (G) represents the total number of pregnancies a woman has had, regardless of the outcome. Para (P) indicates the number of pregnancies that reached a viable gestational age (usually 20 weeks or more), which can be further divided into live births and stillbirths. Abortus (A) accounts for the number of pregnancies that ended in miscarriage or elective abortion before reaching the age of viability.

This structure provides a concise overview of a patient's reproductive history, which is crucial for managing obstetric care and understanding potential risks during pregnancy. The other provided options do not accurately reflect the standard medical terminology or the components that G/P/A is meant to quantify.
