Liver tests


There are some liver testswhich can give you an idea of ​​the health of this organ. The liver is the largest gland in the human body and performs a large number of functions. Theblood tests to check the liverare different and your doctor should prescribe them for you.

What are the tests for the liver so as to investigate the health conditions of this organ. From blood anal to instrumental tests.

Liver tests

If you have any doubts about your healthliver, talk to your doctor, report isymptomsthat you feel or your simple worries. Theblood tests for the liverI'm:

  • Transaminases
  • Alkaline phosphatase
  • GT range
  • Bilirubin

Not to be overlooked atspecific examslike theultrasoundwhich can detect an enlargement known as "fatty liver", very common among those with problems withhyperlipidemias(high cholesterol and triglycerides).

Putting aside the ultrasound and other instrumental tests, let's focus on what they arespecific blood tests to check the state of health of the liver.

The results of these analyzes must be evaluated as a whole. Self-diagnosis is absolutely not recommended. A good hepatologist will be able to assess the situation and, if necessary, prescribe a treatment.

Transaminases

ThetransaminasesI'menzymes present in abundance in liver cells. The values ​​oftransaminasesgive an indication of the state of health of the liver but when this organ is fine, any imbalances may reflect the health of other organs such as theheartor the skeletal system.

Typically, when your doctor prescribesblood analysis, may require an investigation intoALT transaminases(or GPT) which mainly concern the liverand otherstransaminasesknown as "GOT or AST transaminases" which reflect the health of the heart or skeleton.

ALT or GPT

The exam measures the concentration ofALTin the blood. ALT can also be indicated with the initials GPT.

  • ALT =Alanine amino transferase
  • GTP =Glutamate pyruvate transaminase

The examination ofALT or GPT transminaseis prescribed to those patients who present symptoms of an alteration of liver function such as jaundice, dark urine, nausea and vomiting, abdominal pain and swelling ... Or patients with a previous history of alcoholism, drug abuse or who have been exposed to the hepatitis virus.

Normal values ​​in humans: 10-40 U / L

Normal values ​​in women: 5-35 U / L

AST or GOT

The test measures the concentration of AST in the blood, it is also indicated with the initials GOT. AST is an enzyme located mostly in the heart and liver. It is prescribed together with the ALT test and bilirubin to determine the health of the liver.

  • AST = Aspartate amino transferase
  • GOT = Glutamic oxaloacetic transaminase

Normal values ​​in humans: 10-40 U / L

Normal levels in women: 5 - 30 U / L

Alkaline phosphatase

Also indicated with the initials AlPh. It is an enzyme present in various tissues of the body and the blood concentrations are measured with the examination. In particular, alkaline phosphatase is found in bones and liver cells that form the bile ducts, that is, those channels that transport bile to the intestine where it is necessary for the digestion of fats.

Thisblood test for the liverit is especially useful for highlightingillnessesborne by the biliary tract, however it is also used to assess the health of the bones.

Normal values ​​in adults are: 50 - 190 U / L.

GT or GGT range

Is calledGT rangeorGGT he was born in'blood analysiswhich goes to measure the concentration ofgamma glutamyl transpeptidase (GT or GGT). In the presence of liver damage, the amount of GGT in the blood tends to increase.

In particular, the examinationGGT rangetends to be the most "sensitive" to detect problems affecting thebile ducts.

The test can also be used to distinguish between a bone disease and a liver disorder in cases of high levels of alkaline phosphatase, another enzyme that can be measured with a specific test.

The examGGT rangeit is altered in case of prolonged alcohol abuse: it tends to increase in 75% of chronic drinkers.

  • Normal values in men: 6 - 28 U / L
  • Normal levels in women: 4 - 18 U / L.

Bilirubin

The exam measures the concentration ofbilirubinin the blood in three different characterizations. In fact, we speak ofdirect bilirubintotal bilirubinis indirect bilirubin.

An insight into thisvalueyou can have it in the article dedicated tohigh direct bilirubin. Where you will find a lot of information ondifferences between direct and indirect bilirubin. If the liver becomes ill or excess red blood cells are destroyed, the bilirubin in the blood increases.

  • Normal values ​​of total bilirubin: 0.2 - 1 mg / dl
  • Indirect bilirubin: 0.2 - 0.8 mg / dl
  • Direct: 0 - 0.2 mg / dl
