Toxic shock syndrome - Diagnosis 

There is no single test for toxic shock syndrome (TSS). The condition is diagnosed by looking for the typical symptoms and checking for evidence of organ failure.

Organ function can be tested in a variety of ways, including blood and urine tests.

A confident diagnosis of TSS can usually be made when:

• you have a temperature of 38.9 °C (102.02 °F) or more
• you have low blood pressure, fainting and dizziness
• you have a widespread flat red skin rash
• three or more of your organs have been affected by infection

If all of the above are present, it is likely that you have TSS.
