What This Test Measures
This test measures your Cold Agglutinin Titer, quantitatively. Cold agglutinins are autoantibodies that mistakenly target red blood cells, causing them to clump together when exposed to cold temperatures. This can increase the likelihood that your body destroys these affected red blood cells.
The result is reported as a titer, a quantitative measurement of cold agglutinin levels in your blood. This titer helps identify the presence and relative concentration of these autoantibodies, which may contribute to hemolytic anemia when levels are elevated.
Benefits
- Measures cold agglutinin titer levels in your blood
- Supports evaluation of possible cold agglutinin disease
- Provides a quantitative result for tracking autoantibody levels
- Uses a simple blood sample with no special preparation
- Offers a straightforward way to check for cold-reacting antibodies
Who Is This Test For?
- Adults experiencing symptoms consistent with hemolytic anemia
- Individuals noticing bluing in fingers, toes, or ear tips after cold exposure
- People experiencing unexplained fatigue, weakness, or dizziness
- Adults with pale skin or pain of unclear origin
- Individuals whose healthcare provider is investigating hemolytic anemia
- Adults wanting to check cold agglutinin levels as part of a broader evaluation

FAQ
1. What is the purpose of this test?
This test measures your cold agglutinin titer, a quantitative marker of autoantibodies that target red blood cells. It may help a healthcare provider evaluate possible causes of hemolytic anemia and assess for cold agglutinin disease. This test alone does not diagnose a condition.
2. When might I consider ordering this test?
You may consider this test if you have symptoms associated with hemolytic anemia, such as pale skin, fatigue, weakness, dizziness, headaches, or bluing of the fingers, toes, or ear tips after cold exposure. It may also be used when a healthcare provider is investigating the cause of hemolytic anemia.
3. What does this test measure?
This test measures Cold Agglutinin Titer, Quant, using a blood sample. The result is reported as a quantitative titer rather than a simple positive or negative result. It reflects the level of cold-reacting autoantibodies present.
4. Do I need to fast or prepare before this test?
No special preparation, fasting, or dietary restrictions are required before your blood sample is collected.
5. How quickly will I get results?
Results are typically available in 2–4 business days. Weather, holidays, or other laboratory delays may extend this timeframe.
6. How do I interpret the results?
Interpretation depends on the level detected and your individual clinical context. Your healthcare provider may consider your symptoms, medical history, medications, and other laboratory results. An elevated titer does not automatically confirm cold agglutinin disease, and a normal titer does not rule out other causes of hemolytic anemia.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
7. What should I do if my result is outside the expected range?
Review the result with a qualified healthcare provider. They can interpret it in the context of your symptoms and history and determine whether additional evaluation is appropriate.
8. How often should I get tested?
There is no fixed repeat-testing schedule. Follow your healthcare provider’s guidance based on your symptoms and clinical needs.
Pre test preparation
No special preparation is required for this test.
