Frequently Asked Questions
What does "50th percentile" mean?
It means the child is exactly at the median; 50% of children of the same age and sex are heavier/taller, and 50% are lighter/shorter.
What is a "concerning" percentile?
Usually, values below the 5th or above the 95th percentile warrant further investigation by a pediatrician.
Does one measurement tell the whole story?
No. The "trend" or curve over time is much more important than a single data point.
