NIHspeak The closeness of agreement between test results obtained within a single lab when the procedure is performed on the same substance under identical conditions in a given time period. See Reproducibility.


1. the ability to get similar results at a series of examinations.
2. in genetics a measure of the extent to which an animal's superiority (or inferiority), based on an initial measurement, will be seen in future measurements. Denoted by R.
3. in diagnostic tests, the ability of the test to give consistent results in repeated measurements. See also precision.

Patient discussion about repeatability

Q. Now my question is: what kind of repetitive symptoms should I look for? I read the previous question about the early autism symptoms of a child. It is very beneficial. Now my question is: what kind of repetitive symptoms should I look for?

A. It depends upon your child’s health. Repetitive symptoms will vary from child to child but they will begin to show up at a very young age. Look for things such as stacking of items or lining items up compulsively. They may also have repetitive body movements such as hand flapping or body rocking. In some cases, the child may even injure themselves on a regular basis such as by biting their skin. As with most things, each individual child will display repetitive symptoms in their own way.
