Serotonin is a neurotransmitter that plays a vital role in many bodily functions, including mood, sleep, and digestion. Low serotonin levels have been linked to a number of mental health conditions, including depression, anxiety, and obsessive-compulsive disorder (OCD). Therefore, it is important to be able to check serotonin levels in order to diagnose and treat these conditions.
There are a number of ways to check serotonin levels. One common method is to measure the levels of serotonin metabolites in the urine. This can be done through a simple urine test. Another method is to measure the levels of serotonin in the blood. This can be done through a blood test.
