The transition into parenthood comes with its own set of challenges, not the least of which is navigating the scrutiny that often accompanies it. From the moment of birth, parents may feel as if their newborn is being evaluated, and indeed they are, through something known as the Apgar test. If you’re preparing to welcome a little one, you may have come across this term in your parenting literature. Here’s what you need to know about the Apgar score and its significance for your baby’s health.
Understanding the Apgar Test
Developed by Dr. Virginia Apgar in 1952, the Apgar test provides a quick assessment of a newborn’s well-being immediately after birth. The American Academy of Pediatrics explains that it evaluates critical areas such as heart rate and muscle tone to determine whether a baby requires immediate medical attention. The name “Apgar” serves as both a tribute to its creator and a mnemonic for the five components of the test:
- Appearance (skin color)
- Pulse (heart rate)
- Grimace response (reflexes)
- Activity (muscle tone)
- Respiration (breathing rate and effort)
Healthcare professionals conduct the Apgar test at one minute and again at five minutes after birth to gauge how well the baby is adjusting to life outside the womb.
How is the Apgar Score Calculated?
The Apgar score consists of five categories, each receiving a score from zero (the lowest) to two (the highest) based on the observed conditions. The total score ranges from one to ten, combining the individual scores from each category.
Here’s how each category is evaluated, according to MedlinePlus:
- Breathing Effort:
- 0 if not breathing
- 1 if breathing is slow or irregular
- 2 if the baby cries well.
- Heart Rate:
- 0 if no heartbeat
- 1 for a heart rate below 100 beats per minute
- 2 for a heart rate above 100 beats per minute.
- Muscle Tone:
- 0 if the muscles are limp
- 1 for some muscle tone
- 2 for active motion.
- Grimace Response:
- 0 for no reaction
- 1 if there is grimacing
- 2 for grimacing with cough, sneeze, or vigorous cry.
- Skin Color:
- 0 if pale blue
- 1 if the body is pink with blue extremities
- 2 if the entire body is pink.
What Is a Normal Apgar Score?
Apgar scores range from one to ten, with scores between seven and nine typically indicating that the baby is healthy. It’s rare for newborns to score a perfect ten due to common phenomena like blue hands and feet, which are not concerning.
What Does an Apgar Score of 6 Indicate?
Scores between four and six are considered abnormal, suggesting that the newborn might need medical intervention. While these scores indicate potential challenges in adjusting to life outside the womb, they are not as critical as scores below four. A score of seven or higher is reassuring, while a score of three or lower raises significant concern.
Causes of a Low Apgar Score
A score lower than seven often signifies that the baby is still adapting to the outside world. Causes can include a complicated birth or remaining fluid in the airway. Typically, treatment involves oxygen provision and airway clearance, along with physical stimulation to encourage a healthy heart rate. Thankfully, many babies who initially score low often show improvement by the five-minute mark. It’s essential to remember that the Apgar score does not predict long-term health outcomes.
Managing Newborns with Low Apgar Scores
Infants with low scores may experience breathing difficulties. For those scoring below seven, doctors will provide oxygen and clear the airway, potentially leading to resuscitation and lung stimulation.
Does Meconium Aspiration Affect the Apgar Score?
Meconium aspiration occurs when a newborn inhales a mixture of amniotic fluid and meconium during delivery, often resulting in an Apgar score of seven or lower within the first few minutes post-birth due to stress on the baby.

Summary
The Apgar score is a vital tool used by healthcare professionals to assess a newborn’s health immediately after birth. By evaluating five key areas—appearance, pulse, grimace response, activity, and respiration—parents can gain insights into their baby’s transition to life outside the womb. Understanding the scoring system can alleviate concerns for new parents, helping them focus on the joy of welcoming their new child.
