Serotonin TestLab Test

Serotonin Test

GetTested’s Serotonin Test is an at home urine test for people who want insight into serotonin levels and how they may relate to mood, sleep, digestion, focus, motivation and emotional balance.

If you struggle with low mood, poor sleep, anxiety like feelings, digestive discomfort, fatigue, low motivation or emotional ups and downs, this test can help you better understand one important signaling pathway that may be part of the picture. By measuring serotonin, the test provides a focused insight into one pathway that may be relevant when mood, sleep and gut related symptoms overlap.
