Introduction

• Autoimmune diseases occur when the immune system
  attacks healthy cells. There are 80 types, and
  symptoms can vary. Diagnosis can be difficult due
  to overlapping symptoms. The ANA blood test helps
  diagnose autoimmune diseases.

What are Anti-Nuclear Antibodies (ANA)?

• Anti-nuclear antibodies are antibodies that
  mistakenly attack the nucleus of cells in the
  body.
• When these antibodies attack the nucleus, it can
  cause inflammation and damage to the cells.

5
How is the ANA test performed?
Patient's blood is mixed with cells containing
nuclei
ANAs can be observed under a microscope
Healthcare provider takes blood sample from
patient's arm
ANAs in the blood bind to nuclei in cells and
fluorescent dye is added
Laboratory tests blood for anti-nuclear
antibodies using indirect immunofluorescence
method

Auto-Immune Disease and ANA Test

• .

• ANA test is common in autoimmune diseases

• Positive ANA test is not enough for diagnosis

• .

• .

• .

• Examples of autoimmune diseases with positive ANA
  test include SLE, Sjogren's syndrome, RA, and
  systemic sclerosis.

• Diagnosis requires consideration of symptoms,
  medical history, and other test results

7
Limitations of the ANA test

• Positive ANA test doesn't always indicate an
  autoimmune disease.
• ANA test results can change over time, and a
  person who is initially negative may test
  positive in the future.
• Thus, diagnosis should not rely solely on ANA
  test, and healthcare providers should consider
  other factors, such as symptoms and medical
  history.
• ANA test has limitations in diagnosing autoimmune
  diseases and should be used in conjunction with
  other diagnostic tools.

Conclusion

• Diagnosing autoimmune diseases can be difficult
  due to overlapping symptoms. ANA test helps
  indicate their presence but doesn't confirm the
  diagnosis alone. Consult a doctor if experiencing
