The Capurro Method is a clinical technique used in neonatology to estimate the gestational age of a newborn, specifically within the first 48 hours of life. Developed by Dr. Haroldo Capurro in 1978, it is particularly valuable when the last menstrual period (LMP) is unknown or early ultrasounds are unavailable. Assessment Parameters
The method evaluates five physical (somatic) characteristics and, in some versions, two neurological signs:
Skin Texture: Ranges from very thin and gelatinous to thick with deep cracks.
Ear Shape (Pinna): Evaluates how much the edge of the ear is curved or folded.
Mammary Gland Size: Measures the diameter of the palpable breast tissue.
Nipple Formation: Assesses the visibility and size of the areola.
Plantar Creases: Examines the depth and distribution of creases on the sole of the foot. Calculation Variants There are two main ways to calculate the final age:
Capurro A (Somatic-Neurological): Used for healthy newborns; it includes the 5 physical parameters plus 2 neurological signs (the scarf sign and head lag). Formula:
Total Score+2007the fraction with numerator Total Score plus 200 and denominator 7 end-fraction
Capurro B (Somatic Only): Primarily used if the baby is stressed or ill, making neurological testing difficult. Formula:
Total Score+2047the fraction with numerator Total Score plus 204 and denominator 7 end-fraction Clinical Classification
Based on the calculated weeks, newborns are categorized as follows: Post-mature: 42 weeks or more. Full-term: 37 to 41 weeks. Mildly Preterm: 35 to 36 weeks. Moderately Preterm: 32 to 34 weeks. Extremely Preterm: Less than 32 weeks.
While the Capurro Method is a reliable bedside tool with a margin of error of approximately ±8plus or minus 8
days, first-trimester ultrasound remains the Gold Standard for gestational age accuracy. capurro edad gestacionalpdf

The Capurro method is a essential clinical tool in neonatology used to estimate the gestational age of a newborn. Developed in 1978 by Dr. Haroldo Capurro and his team, this method is particularly vital in settings where prenatal data, such as the date of last menstrual period (LMP) or early ultrasound, is unavailable or unreliable. Understanding the Capurro Method
The Capurro test evaluates specific physical and neurological characteristics of the neonate within the first 12 hours of life. By assigning scores to these criteria, healthcare providers can determine the infant's maturity level and classify them as preterm, term, or post-term. Evaluation Criteria
The method typically examines several key physical (somatic) and neurological parameters:
Skin Texture: Ranges from gelatinous/very thin to thick with deep cracks.
Ear Shape (Pinna): Evaluates the degree of incurvation or fold of the outer ear.
Mammary Gland Size: Assessment of the palpable breast tissue diameter.
Nipple Formation: Checks for the presence and elevation of the areola.
Plantar Folds: Examines the presence and depth of creases on the sole of the foot.
Neurological Signs: Includes the scarf sign (arm position across the chest) and head recoil (head lag when pulling to a sitting position). The Two Variants of the Capurro Test
Depending on the newborn's clinical status, two different versions of the test are applied:
Capurro A (Somatic-Neurological): Used for healthy newborns or when there is no neurological dysfunction. It combines 4 physical signs with 2 neurological signs. The Capurro Method is a clinical technique used
Capurro B (Somatic Only): Primarily used if the newborn is in critical condition, neurologically depressed, or over 12 hours old. It relies solely on 5 physical signs. Calculation and Formula
To calculate the gestational age in days, a specific constant (K) is added to the sum of all individual scores, and the total is then divided by 7 to obtain the age in weeks. Formula for Gestational Age Capurro A
(Sum+200)7the fraction with numerator open paren cap S u m plus 200 close paren and denominator 7 end-fraction Capurro B
(Sum+204)7the fraction with numerator open paren cap S u m plus 204 close paren and denominator 7 end-fraction Clinical Significance and Accuracy
While ultrasound remains the "gold standard" for dating pregnancy, the Capurro method is highly valued for its accessibility and low cost, especially in resource-limited environments. It has shown high specificity in identifying small-for-gestational-age (SGA) infants.
However, clinicians should be aware that the method may have a margin of error ranging from 9 to 18 days and may be less sensitive for extremely premature infants compared to more modern assessments like the New Ballard Score.

This paper summarizes the method, its clinical significance, the scoring system, and its comparison with other methods like the Ballard and Dubowitz scores.

The Capurro method evaluates gestational age through a combination of physical (somatic) and neurological criteria. Unlike other methods that require the infant to be in a specific quiet state, Capurro emphasized signs that could be assessed with minimal disturbance to the infant.
