Why was your baby tested? Your pediatrician had to order the test and would tell you if there is reason for concern. Please discuss this with your baby's doctor and go from there.
Google searches found between 40 and 200 mg/dl, also 40 mg/dL to 150 mg/dL as normal ranges. Erase all doubt and call the Pediatrician.
Out of curiosity, what meter did you use to get a tenth of a milligram per deciliter [mg/dl] reading?
