What Blood Tests Should I Get for Hot Flashes?
The best blood tests for hot flashes are FSH and estradiol (to check for perimenopause or menopause, by far the most common cause) and TSH with free T4 (an overactive thyroid causes heat intolerance and sweating). Fasting glucose and a CBC help rule out blood sugar problems and infection. In men, hot flashes can come from low testosterone.

When to See a Doctor
Seek immediate medical attention if your symptoms are severe, rapidly worsening, or accompanied by warning signs (chest pain, shortness of breath, high fever). Blood tests are a valuable first step, but they don't replace evaluation by a healthcare professional.
