Tests and diagnosisBy Mayo Clinic staff
If you need medical attention due to heat exhaustion, it may be apparent to medical personnel that you have heat exhaustion, or they may take your temperature to confirm the diagnosis and rule out heatstroke. If your doctors suspect your heat exhaustion may have progressed to heatstroke, you may need additional tests, including:
- A blood test to check for low blood sodium or potassium and the content of gases in your blood.
- A urine test to check the concentration and composition of your urine and to check your kidney function, which can be affected by heatstroke
- Blood tests to check for rhabdomyolysis — serious damage to your muscle tissue
- Imaging tests to check for damage to your internal organs
