There are online versions of bipolar tests that professionals consider accurate screening tools that indicate a need to follow up with a mental health professional for more in-depth testing. Healthline specifically recommends the Bipolar Spectrum Diagnostic Scale. Counselling Resource recommends the Tri-Axial Bipolar Spectrum self-test.
The BSDS detects bipolar I, bipolar II and other bipolar-related disorders; however, the results do not indicate to the test-taker which type of bipolar he may have, explains Healthline. The TABS screens for the manic, depressive or mixed episodes typical of bipolar disorder as well as factors that may preclude the disorder, states Counselling Resource. Both encourage follow-up with a professional to assess the test-taker further if the results indicate a probability of bipolar.
