What does a positive ANA with reflex mean?

In most cases, a positive ANA test indicates that your immune system has launched a misdirected attack on your own tissue — in other words, an autoimmune reaction. But some people have positive ANA tests even when they’re healthy.

What do ANA titers mean?

The level to which a patient’s sample can be diluted and still produce recognizable staining is known as the ANA “titer.” The ANA titer is a measure of the amount of ANA in the blood; the higher the titer, the more autoantibodies are present in the sample.

What infections cause a positive ANA?

Conditions that usually cause a positive ANA test include:

  • Systemic lupus erythematosus.
  • Sjögren’s syndrome — a disease that causes dry eyes and mouth.
  • Scleroderma — a connective tissue disease.
  • Rheumatoid arthritis — this causes joint damage, pain, and swelling.
  • Polymyositis — a disease that causes muscle weakness.

What are the symptoms of ANA positive?

Your doctor might order an ANA test if you have symptoms of an autoimmune disease, such as:

  • Joint and/or muscle pain, stiffness or swelling.
  • Tiredness.
  • Recurring or persistent fever.
  • A red rash on the cheeks and bridge of the nose that looks like a butterfly.
  • Weakness.
  • Light sensitivity.

What causes elevated Ana titer?

The normal titer of antinuclear antibody is 1:40; higher titers of this autoantibody can indicate that a person is affected by an autoimmune diseases. Some of the conditions that can cause a high ANA titer include Lupus, scleroderma, and rheumatoid arthritis (WebMD).

What are some causes of a positive ANA test?

Lupus. Lupus causes pain,inflammation and damage to the organs.

  • Scleroderma. Scleroderma causes the hardening and tightening of the skin and connective tissues.
  • Sjogren’s Syndrome.
  • Mixed Connective Tissue Disease.
  • Rheumatoid Arthritis.
  • Dermatomyositis.
  • Raynaud’s Disease.
  • What to do after positive ANA test?

    Talk with your doctor about what your levels mean and how your symptoms may be explained by the presence of ANA. If your ANA test comes back positive, your doctor will need to run more tests in order to help determine if the results are related to a specific condition. The ANA test is especially helpful in diagnosing lupus.

    What is the normal range for an ANA titer?

    ANA is reported as a “titer”. Low titers are in the range of 1:40 to 1:60. A positive ANA test is of much more importance if you also have antibodies against the double-stranded form of DNA.
