Alanine aminotransferase reference values

Alanine aminotransferase reference values – in this post I wanted to compare the reference values presented in the methodological leaflets of various manufacturers of diagnostic tests. The post is informative.

Remember that laboratory test results should be interpreted in relation to the values provided by the laboratory. This post is educational.

What are the standards for alanine aminotransferase? What are the alanine aminotransferase reference ranges? You will find the answer in the table below.

Alanine aminotransferase reference values – summary table

Values refer to determination of serum alanine aminotransferase activity

Manufacturer	ROCHE1	SIEMENS2	ABBOTT3	KIEĆ4	BECKMANN5	MAYO6	CALIPER7	KRAWCZYŃSKI8
Alanine Aminotransferase ALT reference ranges ADULTS U/L	WOMEN <33 MEN <41	10–49	<55	WOMEN 10-31 MEN 10-41	WOMEN <35 MEN <50	WOMEN 7-45 MEN 7-55	NO DATA	5-40
Alanine Aminotransferase ALT reference ranges CHILDREN U/L	NO DATA	NO DATA	NO DATA	NO DATA	NEWBORNS and INFANTS 13 – 45	GIRLS >1 year 7-45 BOYS >1 year 7-55	GIRLS 0-1 year 5-33 1-13 years 9-25 13-19 years 8-22 BOYS 0-1 year 5-33 1-13 years 9-25 13-19 years 0-24	NEWBORNS <49 INFANTS <56 1-3 years <48 4-6 years <36 7-12 years <47

Legend: m – month, d – days, y – years

Dependence of reference values of alanine aminotransferase.

Below I present some infographics regarding reference values for ALT alanine aminotransferase activity.

Remember that when you want to monitor the concentration of a given parameter, the test should be performed in the same laboratory, with the same method. This is very important for observing changes.

Downloadable tables and graphs

I have prepared for you a list of reference values in printable form.
