Bilirubin comes from the breakdown of red blood cells and is excreted by the liver. High levels of bilirubin can cause jaundice, which is a yellowing of the eyes of skin. Jaundice can occur in The proportion of conjugated bilirubin with respect to the total raised bilirubin can give a clue as to cause of jaundice. 20-40% of total: more suggestive of hepatic than posthepatic jaundice . 40-60% of total: occurs in either hepatic or posthepatic causes > 50% of total: more suggestive of posthepatic than hepatic jaundice. Note that if conjugated bilirubin is less than 20% of total then Learn more about the Government response to coronavirus on GOV UK. Home > Services > Bilirubin direct. Bilirubin Direct (Conjugated) Clinical Use: Avoid strong sunlight on sample. High direct in Gilberts syndrome. High indirect in haemolysis: Background: Direct bilirubin (sometimes referred to as conjugated) is the form of bilirubin which has been conjugated with glucoronic acid and is concentration of conjugated bilirubin in the sample. Biological reference range or cut off: Neonates 1‐13 µmol/L Older children (up to 18 years) 1‐8 µmol/L Adult <5 µmol/L A ‘normal’ level in a very young baby could be an artefact of poor conjugating ability and be falsely reassuring. Please repeat when >10 days old (>14d if preterm). Measuring Bilirubin at the lab: scientists measure conjugated bilirubin and report it as (direct bilirubin), and measures total bilirubin values, Normal bilirubin level is a bilirubin value that means there is no diseases could be found in the sources of synthesis, processing, and removing of bilirubin. normal bilirubin values lie between reference ranges, the lower limit, and the upper Raised and heavily unconjugated bilirubin in your blood is abnormal. When this is the only abnormal result, it is seen as a strong indication that you may have GS. Bilirubin levels can, however, fluctuate in GS and it is possible that they can be within the normal range over a period of time. Bilirubin is measured in micromoles per litre (umol Adult total bilirubin reference range < 21 µmol/L; Please refer to GHNHSFT local policy and to current NICE guidelines for up to date information on neonatal jaundice (links below) Age Reference range (µmol/L) < 1 day <103 1- 2 days <137 2 - 5 days <205 5 - 6 days <190 > 6 days <21 Babies with prolonged jaundice (jaundice lasting more than 14 days in term or 21 days in pre-term) require a Liver function tests (LFTs) with unconjugated and conjugated bilirubin levels — should show unconjugated hyperbilirubinaemia (conjugated bilirubin within the normal range and/or less than 20% of total bilirubin) and other LFT results should be normal. Jaundice or icterus describes the yellow staining of the tissues due to an excess of bilirubin - unconjugated or conjugated. Normal serum bilirubin is 3 to 17 micromol/l. Jaundice becomes clinically detectable at levels above 40 micromol/l. Good natural light is required to detect slight clinical jaundice. Tissues which concentrate bilirubin best are those with a high content of elastic tissue Bilirubin is an orange-yellow pigment, a waste product primarily produced by the normal breakdown of haem, which is a component of a protein called haemoglobin. Haemoglobin is found in red blood cells and gives them their characteristic red colour and is used to carry oxygen round the body. Bilirubin is ultimately processed by the liver to allow its elimination from the body. This test
