Navigating life with multiple myeloma means riding a rollercoaster of unknowns. That's why we created Patient Connect, so you could connect with other multiple myeloma patients to ask for advice / hear their story.
Regular blood tests are a crucial part of this ride, providing you and your medical team with critical data on treatment efficacy, disease progression, and your general well-being. Here's your guide to understanding these tests, what they reveal, and how to leverage the results to take charge of your health journey.
Why Blood Tests Matter in Multiple Myeloma
Blood tests are the cornerstone of multiple myeloma monitoring and treatment. Because myeloma affects plasma cells—white blood cells found in bone marrow—your doctor will frequently order blood tests to measure the levels of proteins and other markers that indicate disease activity.
These tests not only help detect the disease’s presence but also monitor how it progresses over time. By tracking specific markers, you can better understand the effectiveness of your treatment and make informed decisions about your health.
Key Blood Tests for Multiple Myeloma Patients
Let's take a closer look at some of the most common blood tests that are part of routine care for multiple myeloma patients:
1. Complete Blood Count (CBC)
What it measures: A CBC test checks your overall health by measuring red and white blood cells, hemoglobin, hematocrit, and platelets.
Why it matters: Multiple myeloma can disrupt normal blood cell production, leading to anemia or low white blood cell counts, which increase infection risk. Regular CBCs help assess these risks and adjust treatment accordingly.
2. Serum Protein Electrophoresis (SPEP) and Immunofixation
What it measures: SPEP measures the levels of various proteins in the blood. For myeloma patients, it’s used to detect and quantify monoclonal (M) proteins, which are produced by abnormal plasma cells.
Why it matters: The M protein level is a key indicator of disease activity. High levels can indicate that the disease is active, whereas lower or stable levels suggest that treatment is working.
3. Serum Free Light Chain Assay
What it measures: This test measures the levels of free light chains (kappa and lambda) in the blood, which are fragments of antibodies produced by abnormal plasma cells.
Why it matters: An imbalance in kappa and lambda levels can indicate disease activity and progression. This test is particularly useful for patients with non-secretory multiple myeloma.
4. Beta-2 Microglobulin (B2M) Test
What it measures: B2M is a protein found on the surface of many cells. High levels in the blood are associated with multiple myeloma.
Why it matters: B2M levels can help determine the stage of myeloma and predict how aggressive the disease might be. Lower B2M levels are often a sign of better prognosis.
5. Calcium and Kidney Function Tests
What they measure: These tests assess calcium levels and kidney function by measuring creatinine and other markers.
Why they matter: Elevated calcium levels are often seen in myeloma patients due to bone breakdown. Monitoring kidney function is essential because myeloma and some treatments can impair kidney health.
Understanding Blood Test Results: Key Terms Explained
Blood test results can be confusing without some medical background. Here are a few key terms to know and understand when reading your blood test results:
M protein (monoclonal protein): A protein produced by myeloma cells. Tracking M protein levels helps assess disease activity.
Plasma cells: White blood cells that produce antibodies. In myeloma, plasma cells are abnormal and multiply uncontrollably.
Creatinine: A waste product measured in kidney function tests. Elevated levels may indicate kidney problems, which are common in myeloma.
What Do These Results Mean for Your Treatment?
Regular monitoring of blood tests helps you and your healthcare team determine how well your current treatment is working and when adjustments are needed. Here’s how different results might impact treatment decisions:
Stable M protein levels: If your M protein levels are stable, it’s often a sign that the treatment is effective, and your myeloma is under control.
Increasing M protein levels: Rising levels may indicate a need for a treatment change or more aggressive therapy.
Decreasing kidney function: This may require treatment adjustments to prevent further damage.
Tips for Discussing Blood Test Results with Your Healthcare Team
Being proactive in discussing your blood test results can help you feel more in control. Here’s how to approach these conversations:
Ask questions: Understanding your numbers is key. Ask your healthcare team to explain anything unclear in your results.
Track trends: Monitoring trends over time is more meaningful than focusing on a single result. Use a journal or app to keep track of your blood test results.
Understand your options: If results suggest a change in treatment, ask about the options and why they may be better suited to your needs.
Practical Tips for Managing Health Between Blood Tests
While blood tests provide valuable information, there are additional steps you can take to support your health in between tests:
1. Maintain a Balanced Diet
Staying hydrated and eating a balanced diet with adequate protein can support kidney health and help manage myeloma symptoms. Avoid high-calcium foods if your blood calcium levels are elevated.
2. Stay Physically Active
Regular, moderate exercise can help maintain bone health, reduce fatigue, and improve overall well-being. Discuss any exercise plan with your doctor to ensure it’s safe.
3. Stay Informed and Seek Support
Knowledge is power. Staying informed about myeloma and how blood tests impact your care can alleviate stress. Support groups, both in-person and online, offer invaluable community and encouragement.
4. Know Your Symptoms and Report Changes
If you notice new or worsening symptoms, inform your healthcare team promptly. Early intervention can prevent complications and improve outcomes.
Frequently Asked Questions about Multiple Myeloma Blood Tests
How often should I have blood tests for multiple myeloma?
The frequency of blood tests depends on your disease stage, treatment plan, and overall
health. Typically, patients undergoing active treatment may have tests every month, while those in remission may need them less frequently.
What should I do if my blood test results are abnormal?
An abnormal result doesn’t always mean a problem. It’s essential to review trends over time and consult your doctor before making any assumptions.
Can lifestyle changes impact my blood test results?
Absolutely. Diet, hydration, and exercise can all play a role in your health. However, any changes should be discussed with your healthcare team to ensure they’re appropriate for your situation.
Final Thoughts: Staying Empowered Through Knowledge
Understanding and regularly monitoring your multiple myeloma blood tests is a powerful way to stay informed and engaged in your healthcare journey. These tests offer a window into your body’s response to treatment and overall health. By learning about each test’s purpose and meaning, asking informed questions, and adopting a proactive approach to health management, you can actively contribute to your well-being.
Remember, each patient’s journey with multiple myeloma is unique. Keeping a close eye on your blood test results and maintaining open communication with your healthcare team will help you navigate this journey with greater confidence and resilience.
