What is a C1 Esterase Inhibitor (C1-Inh) Test in Bangalore ?

The C1 esterase inhibitor (C1-INH) test measures the level and function of the C1-INH protein in your blood. C1-INH helps control parts of the immune system and prevents excessive swelling. If the protein is low or does not work, the body can produce too much bradykinin, causing sudden swelling episodes. This test helps detect hereditary angioedema and acquired angioedema. Doctors use it to confirm a diagnosis, decide on emergency care for airway swelling, and plan long-term prevention. It is often ordered with C4 and other complement tests to give a complete picture and may be used for family screening when hereditary disease is suspected.

Why Take a C1 Esterase Inhibitor (C1-Inh) Test in Bangalore ?

C1 ESTERASE INHIBITOR (C1-INH) is commonly ordered with complement C4 as part of an angioedema workup when someone has unexplained recurrent swelling, abdominal pain, or breathing difficulty. It helps diagnose hereditary or acquired angioedema and distinguishes low protein levels from dysfunctional protein. Abnormal results may stem from genetic mutations, autoimmune or blood disorders, or related medical conditions, and a family history of angioedema makes testing especially important.

Frequently asked questions

What does it mean if your C1 esterase inhibitor is high in Bangalore?plus

Elevated C1 esterase inhibitor usually reflects an acute‑phase response or hormonal states (pregnancy, estrogen therapy), liver disease, infection, or recent C1‑INH replacement therapy. It is not typical for hereditary angioedema, which shows low or dysfunctional C1‑INH. Interpretation depends on clinical context; your clinician may order C4 and C1‑INH functional assays and review medications and conditions to determine significance.

How is C1 angioedema treated in Bangalore?plus

C1‑esterase inhibitor deficiency (bradykinin‑mediated) angioedema is treated acutely with C1‑INH concentrate, icatibant (bradykinin B2 blocker) or ecallantide; fresh frozen plasma can be used if specific agents are unavailable. Airway protection and emergency care are essential. For prevention, regular C1‑INH replacement, lanadelumab or oral berotralstat are options; attenuated androgens or tranexamic acid are alternatives. Antihistamines, steroids and epinephrine are generally ineffective.

What are C1 inhibitor drugs in Bangalore?plus

C1 inhibitor drugs are replacement (plasma‑derived or recombinant) proteins that restore C1 esterase inhibitor activity. They block complement and contact‑system enzymes (kallikrein, FXII), preventing bradykinin‑mediated angioedema. Used to treat acute hereditary angioedema attacks and for short‑ or long‑term prophylaxis, they are given IV or subcutaneously depending on the product. Adverse effects can include infusion reactions and, rarely, thrombotic events.

Is C1 deficiency an autoimmune disease in Bangalore?plus

C1 inhibitor (C1-INH) deficiency is usually a genetic disorder (hereditary angioedema) caused by SERPING1 mutations, not an autoimmune disease. However, an acquired form exists where autoantibodies against C1-INH cause low C1 levels; this acquired deficiency is often associated with autoimmune or lymphoproliferative conditions. Diagnosis and treatment differ between hereditary and acquired forms.

What is the normal range for C1 esterase inhibitor in Bangalore?plus

Normal C1 esterase inhibitor levels are reported two ways. Antigenic (protein) concentration is typically about 21–39 mg/dL (0.21–0.39 g/L). Functional activity is usually expressed as a percentage, with normal roughly 70–130% (lab-dependent); activity below about 50–60% generally indicates deficiency and may merit further evaluation for hereditary or acquired angioedema.

What are the symptoms of acquired angioedema in Bangalore?plus

Acquired angioedema causes sudden, painless swelling of the face, lips, tongue, throat, eyes, hands and feet. Swelling often occurs without itching or hives. Laryngeal involvement can cause hoarseness, stridor or breathing difficulty and may be life‑threatening. Abdominal attacks cause severe cramping, nausea, vomiting and diarrhea from intestinal wall swelling. Episodes develop over hours and may recur.
