Jaundice since D 2 of life

Total Bilirubin 25 mg% Indirect Bilirubin 23. 2 mg%

High Indirect Bilirubin Direct coomb’s test Positive Coomb’s test negative Increased Hb/Haematocrit. Delayed cord clamping Maternal foetal or twin – twin transfusion Isoimmunization Rh incompatibility ABO incompatibility Minor group incompatibility Normal / Low – Hb/Hct. RBC Morphology abnormal High reticulocyte count. ABO RBC – normal Reticulocyte count – normal. Extravascular incompatibility G 6 PD deficiency α – thalassaemia Spherocytosis / Elliptocytosis Disseminated intravascular coagulation (D. I. C. ) blood - Cephalhaematoma, Bruises Increased entero – hepatic circulation Pyloric stenosis Intestinal obstruction Swallowed blood Metabolic / Endocrine problems Criggler – Najjar syndrome Hypothyroidism Breast milk jaundice etc

No hematoma No blood group incompatibility No evidence of sepsis No evidence of hemolysis CBC/PS/Retic’s/G 6 PD/DCT LFT normal TFT normal
