What is primary immune deficiency?
People with primary immunodeficiency (PI) have an immune system that does not work correctly. This means that people with PI are more likely to get and become very sick from infections. There are more than 400 types of PI that vary in severity, which affects how early they are detected.
Can blood test detect low immunity?
Blood tests can determine if you have typical levels of infection-fighting proteins (immunoglobulins) in your blood and measure the levels of blood cells and immune system cells. Having numbers of certain cells in your blood that are outside of the standard range can indicate an immune system defect.
What blood tests are done to check for autoimmune disorders?
The antinuclear antibody (ANA) immunofluorescence assay (IFA) is a first-line screening test for patients with a suspected autoimmune disease. This test is the gold standard because of its high sensitivity compared to other assays.

Signs and symptoms of primary immunodeficiency can include: Frequent and recurrent pneumonia, bronchitis, sinus infections, ear infections, meningitis or skin infections. Inflammation and infection of internal organs. Blood disorders, such as low platelet count or anemia.
What are the causes of primary immunodeficiency?
PIDDs are caused by genetic abnormalities that prevent the body from developing normal immune responses. Most often, genetic mutations run in families. Several types of inherited mutations can cause PIDDs.
What conditions make you immunosuppressed?
Severe immunosuppression includes people who had or may recently have had: a blood cancer (such as leukaemia or lymphoma) a weakened immune system due to a treatment (such as steroid medicine, biological therapy (sometimes called immunotherapy), chemotherapy or radiotherapy. an organ or bone marrow transplant.
Can you cure primary immunodeficiency?
For some primary immunodeficiency disorders (PIDDs), these therapies can keep children healthy and active for many years. However, none of these therapies can cure the PIDD. The only known cure is hematopoietic stem cell transplantation or gene therapy.
Is primary immunodeficiency a disability?
Although you may not have considered it before COVID-19, primary immunodeficiency or other immunocompromising conditions can qualify you as a person with a disability under the Americans with Disabilities Act (ADA) and its successor, the Americans with Disabilities Act Amendments Act (ADAAA).

What causes immune deficiency?
Immunodeficiency disorders usually result from use of a drug or from a long-lasting serious disorder (such as cancer) but occasionally are inherited. People usually have frequent, unusual, or unusually severe or prolonged infections and may develop an autoimmune disorder or cancer.
What is the treatment for immune deficiency?
Medications and treatments for immune deficiencies include: Antimicrobial therapy to fight and prevent infections. Immune globulin replacement therapy. Vaccinations.
What causes poor immune system?
Your immune system can also be weakened by smoking, alcohol, and poor nutrition. AIDS. HIV, which causes AIDS, is an acquired viral infection that destroys important white blood cells and weakens the immune system. People with HIV/AIDS become seriously ill with infections that most people can fight off.
Overview
- Primary immunodeficiency disorders — also called primary immune disorders or primary immunodeficiency — weaken the immune system, allowing infections and other health problems to occur more easily.Many people with primary immunodeficiency are born missing some of the body's immune defenses or with the immune system not working properly, which leaves them m…
Diagnosis
- Your doctor will ask about your history of illnesses and whether any close relatives have an inherited immune system disorder. Your doctor will also perform a physical examination.Tests used to diagnose an immune disorder include: 1. Blood tests. Blood tests can determine if you have normal levels of infection-fighting proteins (immunoglobulin) in your blood and measure th…
Treatment
- Treatments for primary immunodeficiency involve preventing and treating infections, boosting the immune system, and treating the underlying cause of the immune problem. In some cases, primary immune disorders are linked to a serious illness, such as an autoimmune disorder or cancer, which also needs to be treated.
Causes
- Many primary immunodeficiency disorders are inherited — passed down from one or both parents. Problems in the genetic code that acts as a blueprint for producing the cells of the body (DNA) cause many of the immune system defects.There are more than 300 types of primary immunodeficiency disorders, and researchers continue to identify more. They can be broadly cla…
Coping And Support
- Most people with primary immunodeficiency can go to school and work like everyone else. Still, you might feel as if no one understands what it's like to live with the constant threat of infections. Talking to someone who faces similar challenges may help.Ask your doctor if there are support groups in the area for people with primary immunodeficiency or for parents of children with the …
Symptoms
- One of the most common signs of primary immunodeficiency is having infections that are more frequent, longer lasting or harder to treat than are the infections of someone with a normal immune system. You may also get infections that a person with a healthy immune system likely wouldn't get (opportunistic infections).Signs and symptoms differ depending on the type of prim…
Prevention
- Because primary immune disorders are caused by genetic defects, there's no way to prevent them. But when you or your child has a weakened immune system, you can take steps to prevent infections: 1. Practice good hygiene. Wash your hands with mild soap after using the toilet and before eating. 2. Take care of your teeth. Brush your teeth at least twice a day. 3. Eat right. A hea…
Preparing For An Appointment

Complications
- Complications caused by a primary immunodeficiency disorder vary, depending on what type you have. They can include: 1. Recurrent infections 2. Autoimmune disorders 3. Damage to heart, lungs, nervous system or digestive tract 4. Slowed growth 5. Increased risk of cancer 6. Death from serious infection...
Risk Factors
- The only known risk factor is having a family history of a primary immune deficiency disorder, which increases your risk of having the condition.If you have a type of the condition, you might want to seek genetic counseling if you plan to have a family.
