Hemoglobin Mass Measurement by Flow Cytometry (Whole Blood)

Why This Test Matters

Hemoglobin is the protein in red blood cells that binds and transports oxygen from your lungs to the rest of your body. Low levels can indicate anemia, blood loss, or other conditions affecting red blood cell production or function. This test provides a precise count of hemoglobin mass, which can help diagnose or monitor conditions like iron deficiency, chronic illness, or blood disorders.

When You Might Need It

Your doctor may order this test if you have symptoms like fatigue, pale skin, shortness of breath, or dizziness. It’s also used during pregnancy, before surgeries, or to monitor conditions like anemia, kidney disease, or certain cancers.

Sample Collection and Preparation

A small blood sample is drawn from a vein in your arm. The blood is analyzed immediately using flow cytometry, a technique that separates and counts red blood cells while measuring their hemoglobin content without needing separate hemoglobin testing.

What to Expect Before the Test

No special preparation is needed, but inform your doctor about any medications, recent blood donations, or conditions that might affect results (e.g., recent blood loss, certain medications). Avoid strenuous activity 24 hours before the test if possible.
