What is Normal serum bilirubin level is: and explain in detail?
Ans: c (0.1- 0.5 mg/dl) Ref: Harper, 23th ed, p. 371; Vasudevan, 4th ed, p. 255Answer is option c since a, b, d have values more than one.Normal plasma bilirubin level ranges from 0.2 - 0.8 mg/dl. Of this major fraction is un-conjugated which is about 0.2 - 0.6 mg/dl, while conjugated bilirubin is only 0 -0.2 mg/dl. If plasma bilirubin level exceeds 1 mg/dl, the condition is called hyperbilirubinaemia. The level between 1 and 2 mg /dl are indicative of latent jaundice. Level > 2 mg/dl is jaundice.Direct serum bilirubin: 0.1 - 0.4 mg/dl ( Harper )Indirect serum bilirubin: 0.2 - 0.7 mg/dl ( Harper )Level more than 1 mg/dl is hyper bilirubinemia ( Harper )
