ALT – alanine aminotransferase (GPT)

ALAT – alanine aminotransferase (GPT)

Name: К+31
Telephone: +7 (499) 999-31-31
Price range: ₽₽

ALAT is often found in biochemical analyses. The normal alanine aminotransferase (AT) level is 41 U/L for men and 31 U/L for women. However, slight deviations from the upper limit are not always taken into account in the absence of other signs of pathology in the body (symptoms, changes in related biochemical parameters).

GPT levels primarily assess the functioning of the hepatobiliary system: the liver, bile ducts, and pancreas. They increase in:

All forms of hepatitis (especially during exacerbations of chronic conditions)
Metabolic disorders (hepatosis)
Intoxication (poisoning, severe infections, parasites)
Tumors and metastases to the liver
Obstruction of bile flow (obstructive jaundice)
Pancreatitis

Less specific, but still quite sensitive for common pathological conditions:

Burn disease
Blood diseases
Severe injuries
Use of certain medications (hormone therapy, antibiotics, chemotherapy)

For all of the above-mentioned conditions, alanine AT cannot be the only test used to establish a diagnosis. However, when combined with other results, it significantly facilitates the diagnostic search.

A below-normal level is rare and is typical of deficiency conditions (vitamin, macro- and microelement deficiencies), liver cirrhosis, and poisoning with drugs that have pronounced hepatotoxicity.

Blood tests are necessary if:

Heaviness or pain in the right upper quadrant
Girdle-like pain in the upper abdomen
Nausea after eating and heartburn
Bloating, unstable stools
Loss of appetite
Yellowing of the skin
Prolonged elevated body temperature
Unexplained weakness and severe fatigue

In such situations, ALT is a mandatory laboratory test, along with other tests: AST, bilirubin, amylase, etc.

Ivan Pavlovich is the best therapist I've ever seen. I'm always happy to see him again and again. He's an excellent specialist, polite and courteous in his communications, and answers all questions, explains, and elaborates on his prescriptions when needed. It's clear he's truly passionate about his work and is fully engaged in the process. With deep gratitude and best wishes for good health!

Eroshenko Ivan Pavlovich

He listened to everything, asked a few questions, listened to my lungs, and gave me the results. He didn't insist on procedures that weren't necessary in my case.

Babkova Elena Petrovna

A wonderful doctor, I really liked her. I first met her as part of a home care program. I was feeling very unwell, with a fever, a terrible sore throat, and lost my voice, barely able to speak. Anastasia Olegovna spent a lot of time with me, examined me thoroughly, promptly arranged for a team to come out to take my blood tests, reassured me, and provided immediate recommendations, including on related issues (I had pulse and blood pressure issues). After receiving the test results, Anastasia Olegovna called, adjusted my recommendations, and then called to monitor my condition. Even just talking to her made me feel calmer, as she addressed all my questions and concerns without unnecessary emotion or fuss. I was pleasantly surprised. She's "my" doctor.

Korotkevich Anastasia Olegovna

Good afternoon! I first saw my general practitioner, Irina Vladimirovna, on October 16, 2025, regarding a swollen left leg. Irina Vladimirovna conducted a detailed interview, collecting my medical history, examining and palpating the swollen area of my leg (from my foot to my knee), and performing a general examination. She immediately determined that I most likely had a venous thrombosis. She then referred me for a duplex scan of my lower extremity veins, a phlebologist, and a cardiologist. Irina Vladimirovna explained the treatment plan in great detail and prescribed a special diet. I had my second appointment with Irina Vladimirovna on December 3, 2025, after seeing a phlebologist, cardiologist, and endocrinologist (who also turned out to be highly qualified professionals) following the prescribed treatment. She examined me again and confirmed that I was feeling better and that my treatment was proceeding as planned. During this appointment, she was able to coordinate a uric acid blood test for me with the insurance company, demonstrating genuine patient care. Irina Vladimirovna proved herself to be a true doctor who truly cares about her patients! She is kind, compassionate, explains everything clearly and thoroughly, is always willing to help, and most importantly, knows how to help, what tests to order, and which specialists to refer. I highly recommend this specialist to everyone. I will continue to see her whenever possible.

I've known the doctors in the home care department for several years now, as I often consult with them. Among the doctors, I'd especially like to highlight Mikhail Veniaminovich Andrievsky and Nuriyat Muradovna Efendieva: they are highly professional and compassionate. Anastasia Aleksandrovna Tumanova, head of the home care department at the K+31 Clinic on Lobachevsky, is a wonderful doctor. It's rare these days to find doctors as knowledgeable, empathetic, and always ready to help. The department is very well-run. Recently, the home care department was very helpful in organizing and performing specialized and very complex tests at home. I was pleasantly surprised that K+31 Clinic has contracts with other leading specialized federal medical organizations to perform tests. The logistics were flawlessly organized and top-notch, for which I'm extremely grateful to the department manager, Galina Ivanovna Zharkova, and Sofia Zharkova. I would like to express my special gratitude from the bottom of my heart to hematologist Yulia Nikolaevna Dubinina for her consultations, participation, and tremendous assistance.
