Immunity test or antibody test ( Antinuclear Antibodies test or ANA) is a type of examination performed to measure the level and pattern of immunity in the body against disease attacks.
Under normal circumstances, antibodies play a role in killing foreign substances, such as bacteria and viruses. However, there are certain conditions that cause the immune system to do the opposite, namely turning against the body (autoimmune).
This examination is often used to check or detect autoimmune diseases, one of which is lupus . This disease should not be taken lightly, because it can have fatal consequences. Unfortunately, lupus is often detected too late, so the handling and treatment is often late.
Lupus disease occurs due to chronic inflammation that occurs because the immune or immune system attacks the body’s own cells, tissues and organs, aka autoimmune. The bad news, apart from being too late to realize, this one disease can really attack various parts of the body. Starting from the skin, joints, blood cells, kidneys, lungs, heart, brain, and spinal cord.
Know the Results of the Immunity Test
Normally, the immune system in the body functions to protect against infection or certain diseases. But in people with lupus, the body’s immune system actively attacks and triggers damage to various parts and organs of the body. Unfortunately, the disease which is said to be more common in women is still not known exactly what causes it.
One of the causes of this disease is quite difficult to detect is that the symptoms that appear are usually diverse and general in nature. Not only that, the symptoms that occur can easily come and then go away. Starting from mild symptoms, to severe symptoms often occur interchangeably and cause this condition to be mistaken for other diseases.
Some of the symptoms that often appear as a sign of lupus are pain or swelling in the joints, especially in the arms and legs. Usually, the pain that appears will affect more than two joints and often lasts for a long time. Pain can also occur in the muscles in the body. Apart from pain, lupus is also often characterized by symptoms, such as fever and a red rash, especially on the face around the cheeks.
Lupus also often causes symptoms, such as pain in the chest, hair loss, sensitivity to the sun, mouth sores that won’t heal, swelling that occurs in the glands, legs, or around the eyes. People with lupus also usually feel tired and weak more easily and often experience seizures or other neurological disorders.
Immunity Test Procedure to Detect Lupus
Recognizing a lupus attack can be very helpful to prevent risks, because treatment can be done immediately. Apart from paying attention to the symptoms that appear, lupus can also be recognized through certain tests, one of which is an immunity test, aka an antibody test.
When is the Right Time to Get an Immunology Test?
In fact, no special preparation is needed before an immunity test. After determining the preferred hospital and medical personnel, tests can be started immediately. The steps taken are to take a blood sample from the body for later examination in the laboratory.
A positive test result is if anti-nuclear antibodies are found. However, a positive test result doesn’t necessarily mean you have an autoimmune disease. Some people test positive without having autoimmune diseases, especially women over 65 years.
