A TTT blood test is not a standard blood test. The abbreviation "TTT" most commonly refers to a Tilt Table Test. This is a procedure used to diagnose the cause of fainting or unexplained loss of consciousness, not a blood test itself.
What is a Tilt Table Test (TTT)?
A tilt table test (TTT), also known as a passive head-up tilt test or head-upright tilt test, is a diagnostic procedure used to evaluate individuals who experience fainting or syncope. During the test, you lie on a table that is slowly tilted to different angles, mimicking the change in blood pressure that occurs when standing up. Healthcare providers continuously monitor your heart rate, blood pressure, and heart rhythm throughout the procedure. The test helps determine if changes in blood flow are contributing to your fainting spells. [Source: Mayo Clinic, Cleveland Clinic]
- Purpose: To diagnose unexplained fainting or syncope, and orthostatic intolerance. [Source: PMC]
- Method: The patient lies on a table that is tilted to a standing position. Vital signs (heart rate and blood pressure) are monitored continuously. [Source: Mayo Clinic, American Heart Association]
- Advantages: It's inexpensive and non-invasive with a good diagnostic yield. [Source: PMC]
The test is not a blood test; it involves direct monitoring of vital signs while the patient's position is changed. Therefore, there is no blood sample taken.
