Pernicious Anemia Panel by LIA near me in Agra

Pernicious anemia is an autoimmune condition in which the body is unable to absorb adequate vitamin B12 due to immune-mediated damage to stomach cells and intrinsic factor, a protein essential for B12 absorption. This leads to reduced red blood cell production, neurological symptoms, fatigue, and long-term complications if left untreated. Early diagnosis is important to prevent irreversible nerve damage and severe anemia.

The Pernicious Anemia Panel by LIA is a blood test panel used to check if your body is unable to absorb vitamin B12 because of an autoimmune problem (when the immune system attacks your own body). The test looks for two antibodies: Parietal Cell Antibodies (PCA) IgG, which can damage the stomach cells that help produce intrinsic factor, and Intrinsic Factor (IF) Antibodies, which block vitamin B12 from being absorbed. IF antibodies are highly specific for pernicious anemia.

Parietal Cell Antibodies (PCA) were first identified in patients with pernicious anemia (Addison’s anemia) and may also be found in other autoimmune conditions such as Hashimoto's thyroiditis, Type 1 diabetes mellitus (seen in about 20–30% of cases), and chronic atrophic gastritis type A. Intrinsic Factor (IF) antibodies are most commonly detected in pernicious anemia, especially in individuals over 60 years of age. They may also be present in chronic atrophic gastritis type A and autoimmune thyroid disorders, and their presence suggests an increased risk of developing vitamin B12 deficiency.

A doctor may suggest this panel in individuals with unexplained vitamin B12 deficiency, megaloblastic anemia, chronic fatigue, pallor, breathlessness, or neurological symptoms such as numbness, tingling, memory issues, or balance problems. It is also recommended for people with autoimmune disorders, chronic gastritis, or a family history of pernicious anemia.

No special preparation is required for this test. Eat and drink as per the daily routine. However, let the doctor know about all the medications you are taking, as some can affect the test results.

Test result ranges may vary across laboratories depending on the methodology and laboratory-specific guidelines. Do not self-medicate. Always consult your doctor to understand your test results correctly.
