Fatigue should not be confused with general tiredness. Fatigue can occur due to many medical as well as lifestyle conditions ranging between mild and severe.

There may be an imbalance in your body mass index. In many people, fatigue is experienced due to lack of iron or electrolytes. Different fatigue tests are available to pinpoint different deficiencies. A blood sample is needed for that. The process is quite simple. A phlebotomist will draw the blood from your arm and then submit it to our lab. For a fatigue test, you can go for a “basic screening package with iron studies and Hba1c”, “low on energy package”, or “complete hemogram”.
