Gilbert's Syndrome and Military Service: Bilirubin at the Board

The short answer: Gilbert's syndrome does not prevent conscription. The regulation names the condition outright — "enzymopathic (benign) hyperbilirubinaemias" — and places it in clause «v» of article 59 with category B-3. The logic is simple: the article is built on functional impairment, and in Gilbert's syndrome liver function is preserved however high the bilirubin reading.

Which fitness category Gilbert's syndrome yields

What article 59 says verbatim

The wording of clause «v» leaves little room for interpretation:

Clause «v» covers: chronic gastritis and gastroduodenitis with minor impairment of secretory function and rare exacerbations; biliary dyskinesia; enzymopathic (benign) hyperbilirubinaemias; chronic cholecystitis, gallbladder cholesterosis, pancreatitis with rare exacerbations and good treatment results.

Gilbert's syndrome is the classic enzymopathic hyperbilirubinaemia: an inherited deficiency of the enzyme that conjugates bilirubin. That is why it sits alongside biliary dyskinesia rather than alongside hepatitis.

Why high bilirubin does not change the category

This is the main source of expectation and disappointment. The bilirubin figure in a biochemistry panel can run well above the reference range, especially after fasting, exertion, poor sleep or an infection — and the category still remains B-3. The regulation assesses liver function, not a single value: in Gilbert's syndrome the liver works, ALT and AST are normal, and there are no signs of damage.

Where raised bilirubin accompanies genuine liver damage, that is a different story and different clauses. How the situations differ and what is actually examined is covered in the piece on which tests check the liver.

What clauses «b» and «a» cover

For completeness — how Gilbert's syndrome differs from conditions yielding categories V and D. Clause «b» covers compensated cirrhosis, chronic hepatitis with impaired liver function or moderate activity, chronic cholecystitis and pancreatitis with frequent (2 or more a year) exacerbations. Clause «a» covers decompensated cirrhosis, progressive active hepatitis and severe recurrent pancreatitis.

The regulation separately specifies how hepatitis must be confirmed: by a comprehensive work-up in a specialised unit and the results of a needle biopsy, or, where biopsy is impossible or refused, by clinical, laboratory and instrumental data showing stable liver involvement over at least 6 months.

What your records must contain

• A biochemistry panel with bilirubin fractions: in Gilbert's syndrome the unconjugated (indirect) fraction is raised.
• Normal ALT, AST and GGT — evidence of preserved function; what a GGT test shows is worth understanding in advance.
• A UGT1A1 genetic test, if performed — the most precise confirmation of the diagnosis.
• An abdominal ultrasound with no signs of liver involvement.
• Exclusion of viral hepatitis by serology; chronic hepatitis is assessed differently and carries its own code, for example B18.

What is usually missing

• There is one test with high bilirubin but no fractions — indirect and direct are not separated.
• ALT and AST were not measured, so preserved liver function cannot be shown.
• Viral hepatitis has not been excluded.
• The diagnosis reads "hyperbilirubinaemia" without stating its nature, while the regulation requires the benign enzymopathic form specifically.
• Yellowing of the sclerae is recorded as a complaint but never linked to a bilirubin measurement; what generally lies behind jaundice is covered separately.

Questions for your doctor

• Which bilirubin fraction is raised in my case — direct or indirect?
• Are ALT, AST and GGT within range?
• Was a genetic test for Gilbert's syndrome performed?
• Has viral hepatitis been excluded?
• Is the diagnosis recorded specifically as a benign hyperbilirubinaemia?

Liver and bilirubin at departmental boards

The above concerns assessment under Government Decree No. 565. The Interior Ministry, National Guard, Federal Security Service and Emergencies Ministry use their own schedules of diseases, where requirements may differ. A review under article 59 shows how complete your records are but is not their regulation.

The short version

Gilbert's syndrome is named in article 59 directly and placed in clause «v» — category B-3, fit to serve. High bilirubin readings do not change that, because the regulation assesses liver function rather than a single value. Something else is more useful: assembling records that confirm the diagnosis unambiguously — bilirubin fractions, normal liver enzymes and, where possible, a genetic test. Only the military medical board determines the fitness category.
