The DNA MAO test is a focused DNA single test that carefully analyzes the MAOA gene to reveal how this specific gene affects the handling of important neurotransmitters such as dopamine, serotonin and norepinephrine in your body. This test is ideal for those looking for specific genetic information, but many choose to include it as part of our DNA Kombo x3 to combine three DNA tests at a bargain price. While the DNA MAO test offers valuable information about a single gene, the DNA Kombo x3 offers the possibility to combine several DNA tests to be able to find out a large number of genes at a better price. If you want to measure your levels of serotonin, dopamine and other neurotransmitters, the neurotransmitter tests Bas or Plus can be interesting.
