Below is a list of the most important blood tests for mental health. This list is by no means exhaustive - but it is a good start to rule out some basic deficiencies or other causes for poor mood, energy or anxiety.

Please note: blood tests are a moment in time. Some of these levels (such as TSH) may fluctuate daily and even at different times of the day. Discuss the results with your doctor and have them re-tested if necessary.

Remember - everyone is an individual! There is not one solution to depression, anxiety or other mental health issues.

Did you know there is no physical test to diagnose mental health issues?

There are some biological markers that have been associated with poorer mental well-being (depression and anxiety for example).

Because the way we feel mentally - is highly governed by our physical body - sometimes we feel 'low' due to a physical cause (hormones anyone??).

Physical illness causes us to want to withdraw, not be social and have low energy.
