When to Seek Prompt Care

Contact your doctor if you have symptoms of anemia, such as severe fatigue, dizziness, pale skin, or shortness of breath. Seek immediate medical attention if you notice blood in your stool or black, tar-like stools, as this could indicate significant blood loss.

What It Measures

This test checks how much iron and vitamin B12 are in your blood. These are important for making healthy red blood cells. They also help your nervous system work correctly.

Why It's Ordered

Your doctor orders this test to look for different kinds of anemia. This is especially true if you feel tired or weak. It also helps if you have other signs of low iron or low vitamin B12.

Reference Range

Reference ranges for iron and vitamin B12 can vary between different laboratories. Your doctor will interpret your results based on these specific ranges and your overall health.
