blood ammonia is commonly used as a liver and biliary tract function test.
true
false

Explanation:

Blood ammonia levels are not typically used as a direct liver and biliary tract function test. Liver function tests usually include measures like alanine transaminase (ALT), aspartate transaminase (AST), bilirubin, albumin, etc. Biliary tract function can be assessed through imaging (like ultrasound, MRCP) or other specific markers. Blood ammonia is more relevant in conditions like hepatic encephalopathy (where liver failure leads to impaired ammonia metabolism, but it's not a standard "function test" in the traditional sense for liver and biliary tract assessment).

Answer:

False
