Does this test have other names?
Alanine aminotransferase, serum glutamic-pyruvic transaminase, SGPT
What is this test?
This test measures the amount of the enzyme alanine aminotransferase (ALT) in your blood.
ALT, formerly called SGPT, is mostly found in your liver cells. When liver cells are injured, they release this enzyme into your blood. High levels are a sign of liver damage.
This test is part of a group of tests commonly referred to as "liver function tests." Results of these tests give healthcare providers an overall picture of how well your liver is working.
Why do I need this test?
You may have this test to see if you have liver damage or a liver disease, such as hepatitis. Symptoms of liver diseases include:
Extreme tiredness or weakness
Loss of appetite
Yellowing of the eyes and skin (jaundice)
Dark yellow urine or light-colored stool
Belly (abdominal) pain
Nausea and vomiting
You may also have this test to look for cirrhosis, which causes damage and scarring to the liver. Causes of cirrhosis include long-term hepatitis infection, excessive alcohol use, obesity, and exposure to certain medicines or toxins. Symptoms of cirrhosis include:
Abdominal swelling from fluid buildup
Visible blood vessels in the skin
Swelling of the legs, feet, or ankles
Nausea, loss of appetite
Feeling tired (fatigue)
What other tests might I have along with this test?
Your healthcare provider may also order other tests of liver health, including:
Your healthcare provider may also order other tests that measure:
What do my test results mean?
Test results may vary depending on your age, gender, health history, and other things. Your test results may be different depending on the lab used. They may not mean you have a problem. Ask your healthcare provider what your test results mean for you.
ALT levels are normally less than 40 international units per liter (IU/L). Levels above 1,000 IU/L may be a sign of:
The ratio of AST to ALT may also provide helpful information to your healthcare provider. AST levels are normally lower than ALT levels. AST is often higher than ALT in cases such as:
A number of other medical conditions besides liver disease can also cause liver enzymes to rise. These include:
Adrenal gland problems
How is this test done?
The test requires a blood sample, which is drawn through a needle from a vein in your arm.
Does this test pose any risks?
Taking a blood sample with a needle carries risks that include bleeding, infection, bruising, or feeling dizzy. When the needle pricks your arm, you may feel a slight stinging sensation or pain. Afterward, the site may be slightly sore.
What might affect my test results?
Many medicines can affect your test results, as can drinking alcohol. ALT levels may also be higher in people who are obese.
How do I get ready for this test?
Your healthcare provider may ask you to not eat or drink and to not take certain medicines before your blood tests. Be sure your healthcare provider knows about all the medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don't need a prescription and any illegal drugs you may use.
Je, jaribio hili lina majina mengine? Alaminotransferase (AAT) - Serum glutamic-pyruvic transaminase (SGPT) - Ni nini? Mtihani huu hupima kiasi cha enzyme ya alanine aminotransferase (ALT) katika damu yako. ALT (SGPT) ni chembe za ini. Chembe za ini zinapojeruhiwa, huondoa kemikali hiyo kwenye damu. Kiwango cha juu ni ishara ya uharibifu wa ini. Uchunguzi huu ni sehemu ya kikundi cha uchunguzi unaoitwa "uchunguzi wa utendaji wa ini". Matokeo ya uchunguzi huu huwapa madaktari picha ya jumla ya jinsi ini lako linavyofanya kazi. Kwa nini ninahitaji mtihani huu? Uchunguzi huu unaweza kugundua ikiwa una uharibifu wa ini au ugonjwa wa ini, kama vile hepatitis. Dalili za ugonjwa wa ini ni pamoja na: uchovu mkubwa au udhaifu, kupoteza hamu ya kula, rangi ya manjano ya macho na ngozi (jaundice), mkojo wa rangi ya manjano nyeusi au mkojo wa rangi nyepesi, maumivu ya tumbo, kichefuchefu na kutapika, na unaweza pia kufanya mtihani huu ili kutafuta cirrhosis, ambayo husababisha uharibifu na makovu ya ini. Vingine vinavyosababisha ugonjwa huo ni kuambukizwa kwa muda mrefu na ugonjwa wa ini, kunywa kileo kupita kiasi, kuwa mnene kupita kiasi, na kutumia dawa fulani au sumu. Dalili za cirrhosis ni pamoja na: Uvimbe wa tumbo kutokana na mkusanyiko wa maji Mishipa ya damu inayoonekana katika ngozi Uvimbe wa miguu, miguu, au vifundo cha mguu Kutoweza kula, kupoteza hamu ya kula Hisia ya uchovu (uchovu) Ni vipimo gani vingine ninavyoweza kuwa pamoja na mtihani huu? Mtoa huduma wako wa afya anaweza pia kuagiza vipimo vingine vya afya ya ini, ikiwa ni pamoja na: Mtoa huduma yako ya afya anaweza pia kuagiza vipimo vingine vinavyopima: Matokeo ya vipimo vyangu yanamaanisha nini? Matokeo ya uchunguzi yanaweza kutofautiana kulingana na umri wako, jinsia yako, historia yako ya afya, na mambo mengine. Matokeo ya mtihani wako yanaweza kuwa tofauti kulingana na maabara iliyotumiwa. Huenda hazimaanishi kwamba una tatizo. Uliza mtoa huduma yako wa afya matokeo ya mtihani wako yanamaanisha nini kwako. Kiwango cha ALT ni chini ya 40 IU kwa lita moja. Kiwango cha juu cha 1000 IU kwa lita inaweza kuwa ishara ya: Asili ya AST kwa ALT inaweza pia kutoa habari muhimu kwa mtoa huduma yako ya afya. Kiwango cha AST ni chini kuliko kiwango cha ALT. AST ni mara nyingi juu kuliko ALT katika kesi kama vile: Idadi ya hali nyingine za matibabu pamoja na ugonjwa wa ini pia inaweza kusababisha enzymes ya ini kuongezeka. Hizi zinatia ndani: Matatizo ya tezi za adrenal Uchunguzi huu hufanywaje? Mtihani huo unahitaji sampuli ya damu, ambayo huchukuliwa kupitia sindano kutoka kwenye mshipa wa mkono wako. Je, jaribio hili lina hatari yoyote? Kuchukua sampuli ya damu kwa kutumia sindano kunaweza kusababisha hatari kama vile kutokwa na damu, maambukizo, majeraha, au kizunguzungu. Wakati sindano inapochomwa mkono wako, huenda ukahisi uchungu au uchungu mdogo. Baada ya hapo, huenda eneo hilo likawa na maumivu kidogo. Ni nini kinachoweza kuathiri matokeo ya mtihani wangu? Dawa nyingi zinaweza kuathiri matokeo ya mtihani wako, kama vile kunywa pombe. Kiwango cha ALT kinaweza kuwa juu zaidi kwa watu wenye uzito mzito. Ninaweza kujitayarishaje kwa ajili ya mtihani huu? Mtoa huduma wako wa afya anaweza kukuomba usile au kunywa na usichukue dawa fulani kabla ya vipimo vya damu. Hakikisha kwamba mtoa huduma wako wa afya anajua kuhusu dawa zote, mimea, vitamini, na virutubisho unavyotumia. Hii inajumuisha dawa ambazo hazihitaji dawa na dawa zozote haramu unazoweza kutumia.
