Thank you Mitchell. Yes, you are right almost, but the multiple fetuses in utero, do not alter number of parity or gravida.
(ie) the birth of multiples (twins, triplets, etc.) is still just parity 1, regardless of the number of babies.
Let me put it this way: if a Primigravida (can also be called primipara if the pregnancy has reached viabilty)) had a twins and both were born after viability (24 weeks and after) but one expired at birth , then we would have G1 P1 A0 L1 (A0 is to denote that she never had an abortion before so far).
- A 'PRIMIGRAVIDA' is a woman who is pregnant for the first time. This primigravida when goes for abortion , then she is called 'primigravida' and 'Nullipara'. When she goes into a delivery of a viable fetus or fetuses, she is then called: G1 'Primipara'.
-A PRIMIPARA is a woman who has had one pregnancy in which the fetus or fetuses reached the point of viability. The parity or gravida is not doubled because of two fetuses in this current pregnancy. In other words, the number of fetuses in the uterus do not alter the number of parity or G for that particular pregnancy.
- a MULTIPARA is a woman who has had two or more pregnancies in which the fetus or fetuses reached the point of viability.
-A woman who has not carried a pregnaNcy to the point of viability ia called a NULLIPARA.
So in your case, if she was primigravida, the formula goes as G1, PI, A0 (if there was no abortion ever before), L1.
If both fetuses were alive, then, G1 P1 Ao L 2
Sometimes Some of the physicians include term with the letter T.
So now the question is how do we know that there was a multiple fetuses in any one pregnancy?
Some add a 5th digit to the formula/ system of acronym, to denote the multiple fetuses delivered.
We should not confuse this formula with another short system: the TPAL shorthand system is often used:
•T stands for “term” or the number of babies the woman has given birth to from 37 weeks onward
•P stands for “preterm” or the number of babies the woman has given birth to from 20 weeks, or 24 weeks, or whenever the current local “cut-off time” for parity is
•A refers to abortions — either miscarriages or induced abortions
•L refers to the number of living children the woman has, regardless of when they died or how old they were.
I hope I am a little more clearer now.
Thank you one again
