Any other names for this test?
ANA Test, ANA Screen IFA with Reflex to Titer and Pattern IFA Test, ANA with Reflex Test, Antinuclear Antibody Screen Test.
What is the ANA SCREEN, IFA, W/REFL TITER, AND PATTERN lab test?
An
ANA test identifies antinuclear antibodies (ANA) in your blood. Your immune system regularly produces antibodies to help in the battle against illness. Antinuclear antibodies, on the other hand, frequently target the nucleus of every cell and destroy the body's tissues.
The positive results of the ANA lab test mean your immune system has started an inappropriate fight against your tissues, also known as an autoimmune reaction. However, some people test positive for ANA even when they are in good condition.
When is an ANA lab test ordered?
An
ANA test is requested when a person shows signs and symptoms of autoimmune problems. Autoimmune disease symptoms can be unclear and non-specific. And can fluctuate over time, slowly get worse, or vary, between flare-ups and remissions.
Conditions when an ANA test is recommended?
Your doctor will order an ANA lab test to screen for autoimmune conditions, including
- Lupus
- Rheumatoid arthritis
- Scleroderma
- Autoimmune illness
- Sjogren Syndrome
Why is an ANA test needed?
This test is ordered if you have signs and symptoms of an autoimmune illness. An ANA lab test can suggest if you have an autoimmune condition but is unable to identify a specific disorder.
What is the purpose of an ANA Screen blood test?
Antinuclear antibodies are made when the immune system fails to differentiate between its cells and foreign cells.
Autoantibodies are antibodies that attack the body's healthy cells and cause symptoms such as tissue and organ inflammation, joint and muscle soreness, and fatigue. The term "antinuclear" refers to the fact that ANA primarily targets substances found in the nucleus of a cell. The ANA test can identify the presence of these autoantibodies in the blood.
The presence of ANA may indicate an autoimmune condition. The most frequent autoimmune disorders are systemic lupus erythematosus and multiple sclerosis.
Why do I need this test?
You may need this test if you have symptoms of an autoimmune condition. Your doctor will ask you to take this test so that he can check the level of antibodies in your blood. The test results will help your doctor in your treatment.
How should I prepare for an ANA test?
No special preparation is required for an
ANA test. To be on the safe side, inform your doctor about any prescription medications or dietary supplements you are taking. The results of the test could be affected by some drugs, for instance.
- seizure
- heart medications
What happens during this test?
An
ANA test is similar to other blood tests. Your healthcare provider will insert a tiny needle into the vein of your hand. A small amount of blood is collected and put in the test container. Once the needle has passed through the vein.
Is any risk attached to an ANA test?
There is no such harmful risk to this test. However, you may feel a slight discomfort due to in and out motion of the needle. You might also see bruising around that area. The symptoms will go away in two or three days.
How long does this test take?
An
ANA test is done in less than five minutes.
What happens after an ANA lab test?
To stop the flow of blood. Your healthcare provider will wrap the area where the needle went with a bandage or cotton.
Is any other test that is needed besides an ANA lab test?
The
ANA test is one of the most commonly used tests to detect an autoimmune disorder or rule out other conditions with similar signs and symptoms. Other autoantibody tests that can help in the diagnosis are following
- ENA Panel test
- Sed Rate (ESR) test
- C-Reactive Protein test
- Complement test
- AMA test
- Centromere antibody test
- Histone Antibody test
What do the results mean?
The presence of antinuclear antibodies indicates a positive test result. However, a positive outcome does not necessarily indicate disease. Many persons with no disease have positive ANA tests, particularly women over 65.
Certain viral disorders and malignancies, as well as certain medications, have been linked to the formation of antinuclear antibodies.
Your doctor will probably request a variety of tests if they have a suspicion that you have an autoimmune condition. One piece of information your doctor can use to help determine the source of your signs and symptoms is the outcome of your ANA test.
What do the positive test results mean?
If the results are positive. It means there are antibodies present in your blood. Your doctor will ask for several other tests to diagnose your health condition.
What do negative test results mean?
If your results are negative, it indicates that certain autoimmune disorders are not present. Based on your symptoms, your doctor might ask for some other test. Some people with autoimmune illnesses may have ANA test results that are negative but positive for other antibodies.
Anything else I should know about this test?
Do not get panic if your test results are positive. The positive results do not always mean that you have an autoimmune disorder. About fifteen percent of fully healthy people have their ANA test result positive. Such results are known as false positive results.
Your doctor will guide you if such a situation takes place.
