What's this test for?
This test is ideal if you're experiencing symptoms that might suggest blood flow problems, such as unexplained headaches, vision changes, dizziness, or numbness in your extremities. It helps identify if your blood is thicker than normal, which can slow circulation and potentially lead to complications. Many people use this test when they have conditions like certain blood cancers or protein disorders that can affect blood thickness and want to monitor their circulatory health.
What's included in this test?
This test measures serum viscosity, which evaluates how thick your blood is and how easily it flows through your blood vessels. Higher viscosity means your blood is thicker and flows more slowly, which can reduce oxygen delivery to tissues and potentially cause circulatory complications. This measurement is particularly important for detecting conditions that increase protein levels in the blood, such as certain blood cancers or immune system disorders.
What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your blood viscosity level means for your circulation and overall health. These notes include personalized recommendations such as hydration strategies, lifestyle modifications, or whether you should follow up with a hematologist or specialist. You'll also get the standard lab report and can track your viscosity levels over time using our trends feature to monitor how treatments or lifestyle changes are affecting your blood flow.
Who should consider getting this test?
This test is important for people diagnosed with or suspected of having blood cancers like multiple myeloma or Waldenström's macroglobulinemia, conditions known to increase blood thickness. It's also valuable for anyone experiencing unexplained symptoms like severe headaches, vision problems, bleeding issues, or neurological symptoms that might indicate circulation problems. Your doctor may order this if you have elevated protein levels detected in other blood work.
What symptoms indicate I may need this test?
Symptoms that may indicate increased blood viscosity include persistent headaches, vision changes or blurriness, dizziness, confusion, ringing in the ears, or numbness and tingling in your hands and feet. You might also experience nosebleeds, bleeding gums, fatigue, or shortness of breath. These symptoms occur because thickened blood flows more slowly and delivers less oxygen to your tissues.
What does high serum viscosity mean?
High serum viscosity means your blood is thicker than normal and doesn't flow as easily through your blood vessels. This can reduce oxygen delivery to your organs and tissues, potentially causing headaches, vision problems, and fatigue. Elevated viscosity is most commonly associated with conditions that increase blood protein levels, such as multiple myeloma, Waldenström's macroglobulinemia, or other blood disorders that need medical attention.
What causes high serum viscosity?
High serum viscosity is most often caused by conditions that increase protein levels in your blood, particularly immunoglobulins. The most common causes are blood cancers like Waldenström's macroglobulinemia and multiple myeloma. Other causes can include certain autoimmune diseases, dehydration, high red blood cell counts (polycythemia), or conditions that increase fibrinogen levels. These conditions cause the blood to become thicker and more resistant to flow.
How can I support healthy blood flow naturally?
While medical treatment is necessary for conditions causing high viscosity, you can support healthy circulation by staying well-hydrated throughout the day. Regular physical activity like walking or swimming helps improve overall circulation. Eating foods rich in omega-3 fatty acids (like fish, walnuts, and flaxseeds) and staying at a healthy weight can also support cardiovascular health. However, if you have elevated viscosity, these lifestyle measures should complement, not replace, medical care.
What happens if my serum viscosity is abnormal?
If your serum viscosity is elevated, your doctor will likely investigate the underlying cause through additional blood tests and possibly imaging or bone marrow studies. Treatment depends on the cause but may include plasmapheresis (a procedure to remove excess proteins from blood), chemotherapy for blood cancers, medications to reduce protein production, or intravenous fluids for hydration. Your doctor will create a treatment plan specific to your condition and monitor your progress with follow-up testing.
How often should I retest my serum viscosity?
Retesting frequency depends on your underlying condition and treatment plan. If you're newly diagnosed with a condition causing high viscosity, your doctor may test frequently during initial treatment, sometimes weekly or monthly. Once your condition is stable or in remission, testing every 3-6 months is common for monitoring. If you're being treated with plasmapheresis, testing may occur before and after each session to assess effectiveness.
