The reference interval of neonatal total bilirubin is: 0 1 day is 34103 μ mol/l; 1 2 days is103171μ mol/l; 3 5 days is 68 65 438+0 37 μ mol/L.

Bilirubin is an orange pigment, which is the product of decomposition and destruction of aging red blood cells in liver, spleen and bone marrow. Hyperbilirubinemia or jaundice can occur when bilirubin is produced too much or the uptake, binding and excretion of bilirubin by hepatocytes are damaged, and the bilirubin concentration in blood is increased. Bilirubin content can reflect the degree of liver cell injury.

The determination of total bilirubin in blood is widely used as a general survey of liver function, and it is one of the most important examination items for diagnosing hepatitis, biliary tract diseases and differentiating jaundice.
