These measure changes in the levels of blood cells or proteins that may mean you have cancerous cells in your bone marrow.</p><p>Read on to learn about the blood tests for multiple myeloma, including what their results mean and how doctors use them to aid diagnosis.</p><h2>Complete blood count</h2><p>A complete blood count (CBC) is a common blood test done to measure the levels of blood cells that are part of your immune system, such as:</p><ul><li>red blood cells, including oxygen-carrying hemoglobin and the percentage of red blood cells in your blood (hematocrit)</li><li>white blood cells that can increase in number when you have cancer or an infection</li><li>platelets that control blood clotting and can suggest illness when they change in levels</li></ul><p>With multiple myeloma, your red blood cells and platelets might decrease as your bone marrow loses its ability to produce enough of these blood cells.</p><p>Your white blood cells might increase in early stages of multiple myeloma but also decrease as cancer affects your bone marrow.</p><h2>Blood chemistry profile</h2><p>With a blood chemistry profile, healthcare professionals use a blood sample to monitor levels of substances in your blood that multiple myeloma can affect, including:</p><ul><li>calcium, which can rise to very high levels when you have multiple myeloma</li><li>albumin, which can lower drastically when you have aggressive forms of multiple myeloma</li><li>creatinine, which can increase due to kidney complications related to multiple myeloma</li></ul><h2>Quantitative immunoglobulin test</h2><p>A quantitative immunoglobulin test can measure the levels of antibodies in your blood that respond to the presence of cancerous cells and changes in what your bone marrow can produce.</p><p>With multiple myeloma, you’ll </p><p>higher levels of antibodies called immunoglobulins on your test results. </p><p>Kidney disease that develops from multiple myeloma can also cause lowered immunoglobulin levels. Doctors may need to use this test alongside other tests to confirm a diagnosis of multiple myeloma.</p><h2>Electrophoresis</h2><p>A serum protein electrophoresis (SPEP) and immunofixation test — sometimes just called an electrophoresis test — involves placing a blood sample on a piece of paper that’s given an electric shock.</p><p>This test can split up antibodies into visible bands that help a healthcare professional note which antibodies are present.</p><p>When you have multiple myeloma, a doctor may see a band of M proteins made by cancerous myeloma cells on the paper.</p><h2>Serum-free light chain assay</h2><p>A serum-free light chain (SFLC) assay </p><p>diagnose light chain myeloma, a subtype of multiple myeloma. </p><p>Doctors often request this test when an electrophoresis test doesn’t show the presence of any M proteins.</p><p>For the SFLC assay test, a healthcare professional will draw a blood sample to test it for the presence of light chain antibodies in your blood. Light chains are a part of what makes up immunoglobulins and are also associated with your blood plasma.</p><p>High levels of light chains in your blood can suggest you have light chain myeloma.</p><h2>Beta-2 microglobulin test</h2><p>The beta-2 microglobulin (B2M) test is a tumor marker test that looks for the presence of B2M proteins in your blood.</p><p>High levels of B2M in your blood can mean you have multiple myeloma or other blood or bone marrow cancers, such as chronic lymphocytic leukemia (CLL) or lymphoma.</p><p>Doctors won’t use the results of a B2M test on its own to diagnose multiple myeloma on its own. But several B2M tests over time can help a doctor figure out how aggressive your cancer is or how well treatments are working.</p><h2>Multiple myeloma symptoms</h2><p>Symptoms of multiple myeloma can depend on what stage you’re in and what organs are affected. Some symptoms you might experience include:</p><ul><li>unexplained shortness of breath</li><li>not peeing as much as usual</li><li>feeling drowsy or fatigued</li><li>confusion</li><li>chest pain</li><li>loss of consciousness or coma</li></ul><h2>Frequently asked questions</h2><h2>What is the most important blood test for multiple myeloma?</h2><p>A complete blood count (CBC) is the most important blood test for multiple myeloma. A CBC test can clearly show levels of immune cells that are directly related to multiple myeloma.</p><p>However, to confirm a diagnosis, doctors will </p><p>to consider results from a serum-free light chain assay along with your symptoms and imaging.</p><h2>Would myeloma show up in a routine blood test?</h2><p>An increase in your red or white blood cells on a routine blood test can mean that you have an active infection or cancer. If a doctor notices an increase in these immune cells, they might order other diagnostic tests to look for other signs of infections or cancer.</p><p>These tests will help them to confirm a diagnosis or rule out conditions.</p><h2>Are blood tests enough to diagnose multiple myeloma?</h2><p>Blood tests are not usually enough to confirm a diagnosis of multiple myeloma. If your blood test results suggest you might have multiple myeloma, a doctor will also perform a biopsy to test a sample of your bone marrow for the presence of cancerous cells.</p><p>Imaging tests, such as a CT scan or MRI, can also help confirm a diagnosis of multiple myeloma with detailed images of the affected bones or organs.</p><h2>Takeaway</h2><p>Numerous blood tests can help diagnose multiple myeloma by showing increased or decreased levels of blood cells and proteins.</p><p>Contact a doctor if you’re concerned that you have multiple myeloma and want help confirming a diagnosis.</p></div></body>
