Interpretation

Reports stating “WITHIN NORMAL LIMIT” means no abnormalities detected in the blood specimen of the newborn.

Reports stating “ABNORMAL” means further tests need to be done to confirm the diagnosis. In some cases, repeat samples are requested as recommendation when another sample will be required to screen the metabolic conditions once again. This is generally practiced to avoid the “FALSE POSITIVE” reports which might be due to various conditions, such as, intrauterine infection, preterm birth, Rh-ve mother and Rh+ baby, antibiotics, degradation of sample, storage and transportation of sample etc.

In case the repeat sample is “ABNORMAL”, confirmatory tests need to be done to confirm and start the treatment immediately. Consulting Metabolic Experts might also be necessary.
