The immunofixation urine test is a common screening measure to evaluate abnormal immunoglobulin levels because the results are available more quickly than they would be with other tests. The immunoelectrophoresis-serum (IEP-serum) test provides similar results.
What does urine Immunofixation mean?
Urine immunofixation is a test that looks for abnormal proteins in urine. In particular, it looks for an abnormal protein known as M-protein. An M-protein is a kind of abnormal immunoglobulin created by plasma cells, which are a type of white blood cells.
What does high Immunofixation serum mean?
Positive results from the test indicate the presence of abnormal Ig. This may suggest the existence of an underlying health condition, such as: an immune system disorder. multiple myeloma. Waldenstrom’s macroglobulinemia.
What is serum Immunofixation test for?
The Immunofixation (IFE) Serum Test detects and identifies monoclonal immunoglobulin gammopathies, which may indicate conditions such as multiple myeloma or Waldenstrom’s macroglobulinemia.What is serum vs urine?
Plasma contains substances including blood cells and certain proteins. Serum is a clear fluid that does not contain these substances. A urine osmolality test is often used along with a serum osmolality test to check the body’s fluid balance.
What is the difference between serum protein electrophoresis and immunofixation?
Serum protein electrophoresis (SPEP) is used to determine the type of each protein present and may indicate a characteristic curve (ie, where the spike is observed). … Immunofixation is used to identify the subtype of protein (ie, IgA lambda).
When should I buy immunofixation?
An Immunofixation test is often ordered when someone has symptoms of diseases such as Multiple Myeloma, Waldenstrom’s Macroglobullinema, Leukemia, Lymphoma, and Multiple Sclerosis.
Can you have multiple myeloma without M protein?
Some people with multiple myeloma don’t make enough M proteins or light chains for tests to show they have it. This is called non-secretory myeloma. A bone marrow biopsy can help diagnose this type of myeloma.Why would a doctor order an Immunofixation test?
This blood test finds out if your body is making or losing protein in abnormal amounts.. It can also tell if you are having problems absorbing protein from foods. This test helps diagnose or check on conditions linked to health problems like the blood cancer multiple myeloma.
What is the most definitive test to confirm a diagnosis of multiple myeloma?Bone marrow biopsy People with multiple myeloma have too many plasma cells in their bone marrow. The procedure used to check the bone marrow is called a bone marrow biopsy and aspiration. It can be done either at the doctor’s office or at the hospital.
Article first time published onIs serum a urine test?
The immunofixation urine test is a common screening measure to evaluate abnormal immunoglobulin levels because the results are available more quickly than they would be with other tests. The immunoelectrophoresis-serum (IEP-serum) test provides similar results.
Is serum hCG more accurate than urine?
The overall efficiency of the two tests was very similar: 99.5% for the serum test, and 97.6% for the urine test. In patients proven to have ectopic pregnancies, however, the serum test was positive in 100%; the urine test was positive in only 60%.
Why is urine preferred over serum pregnancy test?
A first morning urine specimen is preferred since it generally contains the highest concentration of hCG; however, urine specimens collected at any time of the day may be used. Urine specimens exhibiting visible precipitates should be centrifuged, filtered, or allowed to settle to obtain a clear specimen for testing.
Is it good to have no monoclonal protein detected?
If a monoclonal protein is identified, its immunoglobulin class (IgG, IgA, IgM, IgD, IgE) and light chain type (kappa, lambda) are determined by immunofixation. If no monoclonal protein is detected, further testing is not warranted.
Does immunofixation detect light chains?
After recognition of a localized band suggestive of an M protein on SPEP, immunofixation is necessary for confirmation and to determine the heavy- and light-chain class of the M protein.
What does no monoclonal protein detected?
A small number of patients with myeloma have either “oligosecretory disease,” in which the detectable level of monoclonal protein is low, or “nonsecretory disease,” in which no monoclonal protein can be detected.
How is immunofixation performed?
The technique consists of depositing a serum (or urine which has been previously concentrated) sample on a gel. After application of an electric current that allows the separation of proteins according to their size, antibodies specific for each type of immunoglobulin are laid upon the gel.
What does serum protein indicate?
A total serum protein test measures the total amount of protein in the blood. It also measures the amounts of two major groups of proteins in the blood: albumin and globulin. Albumin. This is made mainly in the liver.
How do you read immunofixation?
Immunofixation can either reveal a normal pattern or identify a monoclonal protein or a polyclonal immunoglobulin pattern. A normal result includes a darker immunoglobulin G (IgG) lane, a lighter immunoglobulin A (IgA), an absent immunoglobulin M (IgM), and a denser kappa compared to lambda lane, with ratio of 2:1.
What is usually the first symptom of multiple myeloma?
Signs and symptoms of multiple myeloma can vary and, early in the disease, there may be none. When signs and symptoms do occur, they can include: Bone pain, especially in your spine or chest. Nausea.
Can you have myeloma for years without knowing?
Some people have multiple myeloma for months or years before they even know they’re sick. This earliest phase is called smoldering multiple myeloma. When you have it, you won’t have any symptoms, but your test results will show: At least 10% to 59% of your bone marrow is made up of cancerous plasma cells.
What is Immunofixation electrophoresis?
Immunofixation electrophoresis or immunosubtraction capillary electrophoresis identifies the type of immunoglobulin protein(s) present as monoclonal bands on a protein electrophoresis pattern. Typically, this testing determines the presence and type of monoclonal proteins (e.g., IgG kappa).
When should you suspect multiple myeloma?
Your Doctor May Suspect Multiple Myeloma Before You Do Low red blood cell counts, white blood cell counts, and platelet counts, which are common in multiple myeloma. High levels of calcium in your blood, called hypercalcemia. Abnormal proteins in your blood or urine.
Who is most likely to get multiple myeloma?
Myeloma occurs most commonly in people over 60. The average age at diagnosis is 70. Only 2% of cases occur in people under 40.
At what age is multiple myeloma diagnosed?
Age. The risk of developing multiple myeloma goes up as people get older. Less than 1% of cases are diagnosed in people younger than 35. Most people diagnosed with this cancer are at least 65 years old.

Brown, red, or purple urine Kidneys make urine, so when the kidneys are failing, the urine may change. How? You may urinate less often, or in smaller amounts than usual, with dark-colored urine. Your urine may contain blood.
Can bloodwork determine kidney function?
Know your kidney numbers! Your kidney numbers include 2 tests: ACR (Albumin to Creatinine Ratio) and GFR (glomerular filtration rate). GFR is a measure of kidney function and is performed through a blood test. Your GFR will determine what stage of kidney disease you have – there are 5 stages.
Can you be pregnant and no HCG?
A pregnancy where there is little or no detectable HCG (human chorionic gonadotropin) in the mother’s system and even the fetus may go undetected by doctors, until delivery. HCG is the hormone that makes a home pregnancy test turn positive. A baby that produces very little amount of HCG might fail the pregnancy test.
What should I do if pregnancy test is positive?
Even if you had a positive at home test, it is still necessary for you to see your doctor to confirm you are pregnant. You should make the appointment as soon as possible. Discuss any health issues that could affect your pregnancy like diabetes, hypothyroidism, miscarriages, or other chronic problems.
Which urine is best for pregnancy test?
In the early days of your pregnancy, when hCG levels are still increasing, your first morning urine will offer you the greatest chance of having sufficient hCG levels built up for a positive pregnancy test.
