Quick Facts
- Sample: Blood
- Fasting: No special preparation required
- Turnaround: 3 - 11 business days after setup (testing performed Mondays and Wednesdays); may take longer based on weather, holiday, or lab delays
What This Test Measures
This test measures viscosity (also known as serum viscosity), which reflects the resistance of your blood to flow. The result helps screen for hyperviscosity syndrome, a condition linked to abnormally high levels of red blood cells, white blood cells, or proteins in the bloodstream, or to abnormally shaped red blood cells.
Viscosity is reported as a single measured value from a blood specimen. This test measures blood flow resistance only and does not separately report the red blood cell, white blood cell, or protein levels that can contribute to increased viscosity.
Benefits
- Screens for hyperviscosity syndrome using a single blood specimen
- Helps monitor treatment for conditions associated with hyperviscosity
- Requires no special preparation before testing
- Provides a straightforward measure of blood flow resistance
- Supports ongoing tracking alongside your healthcare provider
Who Is This Test For?
- Adults experiencing symptoms such as headaches, vertigo, or vision problems
- Adults with abnormal bleeding, chest pain, or shortness of breath
- Individuals diagnosed with autoimmune disorders like rheumatoid arthritis or lupus
- Individuals diagnosed with conditions like leukemia, lymphoma, or multiple myeloma
- Adults wanting to monitor treatment for a diagnosed hyperviscosity related condition

FAQ
1. What is the purpose of this test?
This test measures viscosity in a blood specimen to help a healthcare provider evaluate blood flow resistance. It supports screening for hyperviscosity syndrome, a condition linked to increased red blood cells, white blood cells, or proteins in the blood. This test does not diagnose any condition on its own.
2. Who would benefit from this test, and when should I order it?
This test may benefit adults who have experienced symptoms associated with hyperviscosity syndrome, such as headaches, vertigo, or vision problems. It may also be useful for adults previously diagnosed with a condition associated with hyperviscosity who want to monitor changes over time with their healthcare provider.
3. What does this test measure?
This test measures viscosity, a single value that reflects how resistant your blood is to flowing, using a blood specimen. It does not separately identify red blood cell counts, white blood cell counts, or protein levels, and it does not include other tests or specimen types.
4. Do I need to fast before this test?
No special preparation is required before this test.
5. How quickly will I get results?
Results are typically available 3 to 11 business days after setup, as testing is performed Mondays and Wednesdays. Results may take longer based on weather, holidays, or lab delays.
6. How do I interpret the results?
The meaning of your viscosity result depends on your symptoms, medical history, medications, and other laboratory findings. An abnormal result does not automatically confirm a condition, and a normal result does not rule one out.
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 results are abnormal?
If your results fall outside the expected range, review them with a qualified healthcare provider. Additional evaluation or testing may be considered based on your provider’s recommendation.
8. How often should I get tested?
Testing frequency should be determined as directed by your healthcare provider, based on your individual health status and any diagnosed condition. There is no set retesting schedule for this test.
Pre test preparation
No special preparation required.
