Capurro method is a clinical technique used by neonatologists and pediatricians to estimate the gestational age of a newborn, particularly when early ultrasound data or the date of the last menstrual period (LMP) is unavailable
. Developed in 1978 by Dr. Haroldo Capurro Alzola, it relies on specific physical and neurological signs observed shortly after birth. The Story of the Capurro Assessment
In a busy delivery room, a team must quickly determine if a newborn is preterm, term, or post-term to provide the right care. When prenatal records are missing, they turn to the Capurro scale, which transforms physical observations into a precise estimate of weeks. 1. The Physical Inspection (Somatic Parameters) capurro edad gestacionalpdf
The exam begins with a careful look at five physical characteristics, each assigned a point value based on maturity: Skin Texture
: Is it gelatinous and thin (0 points), or thick with deep cracks (20 points)? Ear Shape (Pinna)
: Is the ear flat and shapeless, or is the curve of the upper edge well-defined? Mammary Gland Size
: Is the breast tissue non-palpable, or is there a distinct nodule larger than 10mm? Nipple Formation
: Is the nipple barely visible, or is there a well-defined, elevated areola? Plantar Creases
: Are the soles of the feet smooth, or do they have deep grooves covering more than the anterior half? 2. The Neurological Evaluation
In some versions of the test (Capurro B), two neurological signs are added to the physical ones to improve accuracy: The Scarf Sign
: The clinician moves the infant's elbow across the chest to see how far it goes, testing muscle tone. Head Lag (Headrest)
: The infant is pulled into a sitting position to check if the head follows the trunk or falls back, indicating neck muscle strength. 3. Calculating the Age
To find the final answer, the clinician adds the scores from these signs to a mathematical constant: Capurro A (Somatic only) : Use 204 as the constant. Capurro B (Somatic + Neurological) : Use 200 or 208 depending on the specific protocol. The formula is: Gestational Age (weeks) Total Score
Gestational Age (weeks) equals the fraction with numerator Constant plus Total Score and denominator 7 end-fraction
This simple calculation allows the medical team to decide if the baby needs the specialized environment of a Neonatal Intensive Care Unit (NICU) or can safely stay with the mother. or a list of common medical tools used in neonatal assessments? Methods and materials - EPOS™
The Capurro method is a widely recognized clinical tool used by neonatologists and pediatricians to estimate the gestational age of a newborn. Developed by Dr. Haroldo Capurro and his colleagues in the 1970s, this technique provides a practical alternative for determining fetal maturity, especially in settings where prenatal ultrasound data or reliable menstrual history is unavailable. By assessing specific physical and neurological characteristics, the Capurro method categorizes newborns into different developmental stages, which is critical for identifying potential health risks associated with prematurity or post-maturity.
The method is divided into two primary variations: Capurro A and Capurro B. Capurro A is the more comprehensive version, typically used when the newborn is healthy and shows no signs of neurological distress. It evaluates five physical signs—skin texture, ear shape, mammary gland size, nipple formation, and plantar creases—along with two neurological signs: the "scarf sign" and the "head return" maneuver. Each parameter is assigned a numerical score based on the degree of development. Capurro B, on the other hand, is simplified for use in newborns with neurological depression or those on mechanical ventilation. This version relies solely on the five physical parameters, making it a faster and less invasive assessment for fragile infants.
To calculate the estimated gestational age in days, the total score from the assessment is added to a mathematical constant. For Capurro A, the constant is usually 200, and the sum is divided by 7 to determine the age in weeks. For Capurro B, the constant is 204. For example, if a newborn receives a total score of 70 using the Capurro B method, the calculation would be Headline: 📖 How to master the CAPURRO method
, resulting in approximately 39.1 weeks. This numerical precision allows healthcare providers to classify the infant as preterm (less than 37 weeks), full-term (37 to 41 weeks), or post-term (42 weeks or more).
Despite its utility, the Capurro method has certain limitations. It is most accurate when applied within the first 12 to 24 hours of life, as physiological changes after birth can alter the physical signs used for scoring. Furthermore, while it is highly effective for full-term and moderately preterm infants, its accuracy decreases significantly for extremely premature babies (those under 29 weeks). In such cases, other methods like the Ballard Scale, which includes more detailed neuromuscular criteria, are often preferred.
In conclusion, the Capurro method remains a fundamental pillar of neonatal care in many parts of the world. Its simplicity and lack of requirement for specialized equipment make it an invaluable resource for the immediate clinical assessment of newborns. By providing a reliable estimate of gestational age, the Capurro method ensures that infants receive the appropriate level of medical intervention, ultimately improving neonatal outcomes and supporting early developmental health.
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.
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 Last updated: October 2024
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

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.
For practitioners looking for detailed assessment sheets, official guidelines are often available as a Capurro Method PDF on medical repositories like SciELO or Scribd.
While advanced technology like prenatal ultrasound is the gold standard for dating a pregnancy, medical professionals often find themselves in situations where such data isn't available. In these moments, clinical methods like the Capurro method
become vital tools for assessing a newborn's maturity immediately after birth. What is the Capurro Method?
Developed as a practical alternative for resource-limited settings, the Capurro method uses a specific set of physical and sometimes neurological signs to estimate a newborn's gestational age. It is particularly useful when the mother's last menstrual period (LMP) is uncertain and no early ultrasound was performed. How Does it Work?
The assessment primarily focuses on five somatic (physical) characteristics: Skin Texture:
Ranging from very thin and gelatinous to thick with deep cracks. Ear Shape: The degree of incurvation of the ear's upper edge (pina). Mammary Gland Size: Measuring the palpable nodule. Nipple Formation: Observing the diameter and the appearance of the areola. Plantar Folds: Looking for creases on the soles of the baby's feet. Calculating the Age To find the gestational age in days, a constant (usually
) is added to the sum of the points from these characteristics. This total is then divided by to determine the age in weeks. (Score + 204) / 7 = Gestational Age (weeks) Accuracy and Clinical Use
While it is a cornerstone in many maternity hospitals, studies show that Capurro can sometimes overestimate the age of infants born before 39 weeks or underestimate it in post-term babies. Despite these variations, it remains a highly effective tool for identifying Small for Gestational Age (SGA) newborns, showing high specificity in clinical settings.

Despite its popularity, the Capurro method has significant limitations that every clinician must understand:
Nevertheless, the WHO and UNICEF still recommend Capurro for community-based assessments where ultrasound is unavailable.
