He was diagnosed with Gilbert's syndrome, a rare but benign genetic defect in the liver in which bilirubin conjugation ability may lead to mild jaundice under certain conditions.
Jaundice yellowing of the skin, eyes and mucous membranes due to an impaired ability of the body to clear the by product of haem breakdown, bilirubin, most often the result of liver damage as it is the liver's responsibility to clear bilirubin.
In most cases the LFTs will be consistent with obstruction: raised bilirubin, alkaline phosphatase and γ-glutamyl transpeptidase.
The FibroTest score is calculated from the results of a six-parameter blood test, combining six serum markers with the age and gender of the patient: Alpha-2-macroglobulin, Haptoglobin, Apolipoprotein A1, Gamma-glutamyl transpeptidase (GGT), Total bilirubin, and Alanine transaminase (ALT).
