AB Gestation  is  the  period  of  fetal  development  from  the  time  of  conception  to  birth.  Gestational  age  (or  menstrual  age),  as  defined  by  the  American  Academy  of  Pediatrics  (AAP),  is  the  “time  elapsed  between  the  first  day  of  the  last  menstrual  period  and  the  day  of  delivery.”  Gestational  age  is  expressed  in  completed  weeks  (26-week  and  4-day-old  fetus  is  expressed  as  a  26-week  fetus).  Gestational  age  assessment  is  important  for  the  obstetrician  for  obstetric  care  and  management.  Gestational  age  assessment  is  extremely  important  for  the  neonatologist  for  evaluation  of  the  infant  and  to  anticipate  high-risk  infants  and  complications.  Gestational  age  and  birthweight  classification  helps  the  neonatologist  to  categorize  infants,  guide  treatment,  and  assess  risks  for  morbidity  and  mortality.  Neonates  can  be  classified  based  on  gestational  age  (preterm,  late  preterm,  term,  post  term),  birthweight  (extremely  low  birthweight  [ELBW],  very  low  birthweight  [VLBW],  low  birthweight  [LBW],  etc.),  and  gestational  age  and  birthweight  combined  (small  for  gestational  age  [SGA],  appropriate  for  gestational  age  [AGA],  large  for  gestational  age  [LGA]).  The  AAP  recommends  that  all  newborns  be  classified  by  birthweight  and  gestational  age.
