Liver function tests

• The material for testing is blood.
• Approximately 30 minutes before the examination, it is recommended to drink 1 glass of water only.
• The patient must fast for at least 12 hours after consuming the last meal, unless the doctor recommends otherwise (e.g. performing the test after a meal)
• Before the test you may only drink water.
• You should not drink coffee, flavored water, drinks such as cola light/cola “zero”, energy drinks, or juices.
• You should not eat meals, snacks, fruits, vegetables, breath fresheners, chew gum, or smoke cigarettes.

• For children up to 3 years of age, it is recommended to collect blood half to one hour after feeding.

• For children up to 3 years of age, it is recommended to collect blood half to one hour after feeding.

Total protein – includes all blood proteins. Protein separation is possible thanks to protein electrophoresis.
Due to the ability of proteins to bind water, discrepancies in protein amounts may result from altered hydration (in which case the hematocrit is changed).

The significance of the test: information about the total amount of protein in the body, indicates kidney damage (proteinuria).

Total bilirubin-
abnormal values: liver disease, extreme malnutrition, kidney disease.
It is produced during the breakdown of hemoglobin (from red blood cells). Outside the liver, it is transported by albumin (unconjugated bilirubin). It is excreted from the liver into the intestines via bile (conjugated bilirubin); it gives color to stools. When it is not excreted into the intestines, it enters the bloodstream in increased amounts, giving the whites of the eyes and skin a yellow tint (jaundice). Newborns always develop mild jaundice in the first few days of life.

Importance of the test: confirmation of the diagnosis of jaundice and monitoring of its severity in newborns with prolonged and intense jaundice.

Abnormal values: accelerated or increased destruction of red blood cells, diseases of the liver parenchyma (tumors, inflammation, cirrhosis, congestion, poisoning), bile stasis, e.g. caused by bile duct stones, cholangitis.

AST - found in liver cells, muscle cells (skeletal, cardiac), and kidneys.
Significance of the test: indicates damage to liver cells, muscle cells, and heart muscle.

ALT - is measured when liver disease is suspected, and alongside CPK and LDH when myocardial infarction is suspected.
Abnormal values: liver, muscle, and kidney diseases, myocardial infarction, damage to larger muscle mass.
Present primarily in liver cells, but also in muscle cells, including heart muscle.
With cell damage, it is released into the blood in increased amounts.

Significance of the test: Measured when liver disease is suspected; and in our conditions, alongside other indicator enzymes, CPK
and LDH when myocardial infarction is suspected.

Abnormal values: in diseases of the liver parenchyma, in myocardial infarction.

Ordering a test means consent to its performance using the spectrophotometric method.
