Lab Tests for Anemia
Anemia occurs when your blood doesn't carry enough oxygen to your tissues, causing fatigue, weakness, pale skin, and shortness of breath. It affects over 3 million Americans and has many possible causes, including iron deficiency, vitamin B12 deficiency, chronic disease, and blood loss. Lab testing is essential to diagnose anemia, determine its type, and identify the underlying cause so you can get the right treatment. With JustLabs, you can order a complete anemia workup online at transparent self-pay prices, no doctor visit or insurance required.
