Described is a device for determining gestational age and methods for determining gestational age at birth by measuring parameters associated with photobiological properties of the skin such as reflectance or reflectivity by measuring diffused or scattered portions of the light beam incident on the skin, as well as the erythema index, along with clinical parameters of the newborn such as gender, the use of phototherapy, birth weight and time spent in incubator. The ability to obtain a realistic estimate of the age of the conceptus quickly, non-invasively and at low cost makes it possible to provide care suited to the needs of the newborn, to assess the chances of survival and to affect the short- and long-term prognosis of the newborn. The correct determination of gestational age at birth also influences clinical follow-up protocols in infancy and vital statistics.
