Overview
An elevated concentration of serum bilirubin in neonates in the first 24 hours of life is diagnostic of neonatal jaundice. Transcutaneous bilirubin level measurment can be diagnostic in cases of mild jaundice. Other laboratory tests that can be performed include blood typing and Rh antibodies determination, liver function tests, direct coombs test, serum albumin level, and reticulocyte count.
Laboratory Findings
- An elevated concentration of serum bilirubin is diagnostic of neonatal jaundice.
- Laboratory findings consistent with the diagnosis of neonatal jaudice include:[1]
- Increase of the total bilirubin level more than 5 mg/dl.
- Increase of the conjugated bilirubin level more than 2 mg/dl.
- Transcutaneous bilirubin level measurment can be diagnostic in cases of mild jaundice.
- Other laboratory tests recommended in cases of neonatal jaundice include the following:[2]
- Blood type and Rh antibodies determination in mother and infant
- Direct Coombs test
- Hemoglobin and hematocrit values
- Serum albumin level
- Liver function tests
- Peripheral blood film for erythrocyte morphology
- Reticulocyte count
- Tests for viral and/or parasitic infection
