Why Is This Test Done?
Your healthcare provider may order this test if you have symptoms like fatigue, shortness of breath, pale skin, or unusual weakness. It’s also used to check for conditions such as anemia, blood loss, or other blood disorders. Sometimes, it’s included in routine blood work or during evaluations for suspected blood-related issues.
What Does the Test Involve?
A small blood sample is taken from a vein, usually in your arm. The sample is processed to measure the total hemoglobin content in your red blood cells. This test does not require fasting and can be done at the same time as other blood tests.
What Are Common Uses?
Hemoglobin mass measurement is primarily used to evaluate the overall health of your red blood cells and oxygen-carrying capacity. It can help diagnose types of anemia, monitor chronic diseases like heart failure or kidney disease, or assess the effectiveness of treatments for blood disorders.
What Might Affect Results?
Several factors can influence hemoglobin levels, including recent blood loss, dehydration, certain medications (like blood thinners or iron supplements), pregnancy, or chronic illnesses. If you’re unsure about any medications or conditions, discuss them with your healthcare provider before the test.
Reference range
Adult males: 13.5-17.5 g/dL; Females: 12.0-16.0 g/dLN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
