Aspartate Aminotransferase will not be low, so the results are considered normal. Aspartate Aminotransferase is one of the liver function tests. Aspartate aminotransferase is found mainly in the cytoplasm and mitochondria of heart, liver, and skeletal muscle cells. It is released into the bloodstream when there is damage to the above organs resulting in elevated results. Normally, the reference range for aspartate aminotransferase is 0 to 40 U/L. So there is no possibility of a low result for aspartate aminotransferase, only a possibility of an elevated result, so the result is considered normal. From the aspartate aminotransferase results can not judge whether the organism has abnormalities or not, but also need to be judged under the guidance of the doctor according to other items of liver function, cardiac enzymes, cardiac ultrasound, liver ultrasound and other items.
