GetTested’s **Nutrition Test** is an at home blood test designed to give insight into essential minerals and mineral ratios that may influence **energy, muscle function, hydration, stress response, metabolism, immune function** and **overall nutritional balance**. Mineral imbalances can sometimes be part of the picture when you experience symptoms such as **fatigue, muscle cramps, low energy, poor recovery, weakness, mood changes, headaches** or **feeling generally out of balance**. Since minerals work closely together, this test measures both individual mineral levels and selected mineral ratios for a broader view of nutritional status. By analyzing key minerals in whole blood, the test can help you understand whether your mineral balance may be supporting or challenging important body functions.
