Liver function tests (LFTs or LFs), also referred to as a hepatic panel or liver panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin , bilirubin (direct and indirect), and others.
The cutoff normal individuals from those with primary hyperaldosteronism is significantly affected by the conditions of testing, such as posture and time of day. On average, an ARR cutoff of 23.6 ng/dL per ng/(mL·h), expressed in alternative units as 651 pmol/L per μg/(L·h), has been estimated to have a sensitivity of 97% and specificity of 94%. [2]
Enzyme activity is commonly used for e.g. liver function tests like AST, ALT, LD and γ-GT in Sweden. [5] Percentages and time-dependent units (mol/s) are used for calculated derived parameters, e.g. for beta cell function in homeostasis model assessment or thyroid's secretory capacity.

Aldosterone stimulates Na + and water reabsorption from the gut, salivary and sweat glands in exchange for K +. Aldosterone stimulates secretion of H + via the H+/ATPase in the intercalated cells of the cortical collecting tubules; Aldosterone upregulates expression of NCC in the distal convoluted tubule chronically and its activity acutely.

Screening is usually done by measuring the aldosterone-to-renin ratio in the blood (ARR) whilst off interfering medications and a serum potassium over 4, with further testing used to confirm positive results. [1] While low blood potassium is classically described in primary hyperaldosteronism, this is only present in about a quarter of people. [1]
Fatty liver disease (FLD), also known as hepatic steatosis and steatotic liver disease (SLD), is a condition where excess fat builds up in the liver. [1] Often there are no or few symptoms. [1] [2] Occasionally there may be tiredness or pain in the upper right side of the abdomen. [1] Complications may include cirrhosis, liver cancer, and ...
ALT is usually found only in the liver. AST is most commonly found in the liver, but also in significant amounts in heart and skeletal muscle. [citation needed] Measurement of ALT and AST were used in diagnosing heart attacks, although they have been replaced by newer enzyme and protein tests that are more specific for cardiac damage.
