Any child with an ‘out-of-range’ screening report is considered healthy. If the follow-up test result is within the normal range, it is called a ‘false positive.’ In simple terms, the child does not have a condition that showed up in the test.

A case of false-positive might leave the parents feeling all distressed and scared. Fret not. Take a look at why the results might not be accurately interpreted. Knowing in detail will help you request another examination in case of doubts:

  • The baby has not eaten enough food before the test.
  • The baby does not meet the age criteria or exceed the age for a particular disease
  • Samples taken has been exposed to light and heat
  • Cross-contamination among baby specimens in the lab.
  • The samples were infected by external factors.

Early testing is one of the most common causes of false positives. This might happen if the baby’s nasopharynx or nares are infected by SARS-CoV-2 RNA from the mother’s fluids.
