What is titer testing?

Titer blood tests check your immune status to certain vaccine preventable diseases. A positive result means you have immunity to the disease and do not need to be vaccinated. Many schools and health care workplaces require proof that you have sufficient immunity to these infectious diseases. Titer blood test results provide the required documentation.

What is an immune system disorder?

Immune system disorders are conditions that can cause the immune system to become under active or over active. An under-active immune system becomes less able to fight invaders, like viruses or bacteria, making a person more vulnerable to illnesses and infections. This is called immune deficiency, or immunodeficiency. An over-active immune system attacks and damages the body's own tissues. This is called autoimmune activity, which is the basis of autoimmune disorders/diseases.

What is immune deficiency disorder?

Immune deficiency disorders weaken the immune system, disrupting its ability to defend the body against infections and diseases. There are two basic types of immune deficiency disorder: congenital and acquired. Congenital, or primary, immunodeficiencies are disorders you are born with or that have a genetic (inherited) cause. Serious primary immunodeficiencies are often diagnosed soon after birth, while milder ones may not be discovered until late childhood or even well into adulthood. Acquired, or secondary immune deficiency disorders are ones that you get later in life. Secondary immunodeficiency disorders are more common than primary immune disorders, and their causes can include anything that weakens the immune system, such as:

  • Diabetes
  • Chemotherapy
  • Radiation
  • Severe burns
  • Malnutrition
  • HIV infection
  • Removal of the spleen
  • Aging

Signs of both types of immunodeficiencies can include frequent bouts of illnesses and conditions that either do not respond to treatment, or do not resolve completely over time, including:

  • Colds
  • Sinus infections
  • Ear infections
  • Yeast infections
  • Pinkeye
  • Diarrhea
  • Pneumonia

How do you test for immune deficiency?

If you have symptoms that may indicate immunodeficiency, immune system testing can aid in determining whether or not your immune system is functioning properly. Typically these will include blood tests that:

  • Count your white blood cells – This test measures the overall amount of white blood cells in your blood, which are cells produced by the immune system that fight infections by attacking antigens, such as viruses and bacteria, when they invade the body. Abnormal white cell counts can indicate immune system problems.
  • Count T cells – This tests evaluates your levels of T cells, which are a type of white blood cell that responds to viral infections. Lower than normal levels of T cells can indicate immunodeficiency.
  • Measure your immunoglobulins level – This blood test measures whether or not you have normal levels of immunoglobulins in your blood. Also known as antibodies, there are 5 major types of these proteins produced by the immune system. Abnormal levels of any of them can indicate immune disorders.

Abnormal levels of these infection-fighting immune cells can indicate immunodeficiencies. Vaccines are sometimes used to test for immune deficiency as well. Clinics may administer a vaccine in order to evaluate whether or not the immune system can respond to it appropriately. That evaluation is done via a blood test a few days or weeks after the vaccine is injected. If that blood test finds that your immune system produced antibodies in response to the organisms present in the vaccine, this indicates proper immune function. If no antibodies are found in the blood or levels are extremely low, you may have an immunodeficiency disorder.

What is an autoimmune disorder?

These disorders are caused by an immune system that has become over-active. When this happens, the immune system's infection fighting cells attack tissues and cells within the body as if they were invading viruses or bacteria. This leads to inflammation in those tissues, as well as tissue damage or destruction. Common examples of autoimmune disorders include:

  • Rheumatoid arthritis – In this disorder, the immune system produces antibodies that attack and slowly destroy the linings of joints.
  • Inflammatory bowel disease (IBD) – The immune system attacks the intestinal lining.
  • Multiple sclerosis (MS) – Nerve cells are attacked by the immune system.
  • Systemic lupus erythematosus (lupus) – The immune system attacks tissues in areas that may include the kidneys, lungs, blood cells, joints and nerves.
  • Grave's disease – The immune system attacks the thyroid gland, causing over-production of thyroid hormones.
  • Hashimoto's thyroiditis – The immune system gradually destroys cells that produce thyroid hormones in the thyroid gland.
  • Psoriasis – Overactive immune cells collect in the skin, causing silvery, scaly plaques to develop on the skin in affected areas.
