Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Haptoglobin
A haptoglobin test measures the level of haptoglobin protein in your blood. Haptoglobin binds to free hemoglobin released from damaged red blood cells, and its levels can help assess whether red blood cells are being destroyed faster than normal.
What It Measures
This test measures the concentration of haptoglobin in your blood serum. Haptoglobin is a protein produced by the liver that captures free hemoglobin released during the normal or accelerated breakdown of red blood cells, preventing kidney damage from free hemoglobin.
Why It Matters
Low haptoglobin levels may indicate hemolytic anemia, a condition where red blood cells are destroyed prematurely. This test is valuable in distinguishing between different types of anemia and identifying conditions that cause increased red blood cell destruction.
When to Test
Testing may be recommended when hemolytic anemia is suspected, when investigating unexplained anemia, or as a follow-up to abnormal results on other blood tests such as a complete blood count. Consult a healthcare professional for interpretation of results.
Symptoms
Low Levels
Low haptoglobin may be associated with hemolytic anemia symptoms: fatigue, weakness, pale or yellow skin, dark urine, rapid heartbeat, shortness of breath.
High Levels
Elevated haptoglobin may be associated with inflammation, infection, tissue damage, or certain chronic conditions. Symptoms depend on the underlying cause.
Lifestyle Tips
Maintain a balanced diet with adequate iron and B vitamins to support red blood cell health. Stay hydrated and avoid exposure to substances known to damage red blood cells. If you experience symptoms of anemia, seek medical evaluation promptly.
Frequently Asked Questions
What does a low haptoglobin level mean?
A low haptoglobin level may indicate that red blood cells are being destroyed at a faster rate than normal, a process known as hemolysis. This can be associated with various conditions including autoimmune disorders, infections, or inherited blood conditions. Your healthcare provider will interpret the result in context.
Can haptoglobin levels be affected by other conditions?
Yes, haptoglobin is also an acute-phase protein, meaning its levels can rise during inflammation, infection, or tissue injury. This is why results are often interpreted alongside other blood tests for a comprehensive picture.
