C1 Estrase Inhibitor, Protein Quantitation

3,000.00

The C1 Esterase Inhibitor (C1-INH) Protein Quantitation test measures the amount of C1 esterase inhibitor protein in the blood. C1-INH is a regulatory protein that controls the activation of the complement system, which is part of the immune system.
This test quantifies the protein level of C1-INH to help diagnose or monitor conditions related to C1-INH deficiency or dysfunction.

    Description

    Why It’s Done

    The test is primarily used to:
    1. Diagnose Hereditary Angioedema (HAE)
    • HAE is a rare genetic disorder caused by low levels or dysfunctional C1-INH, leading to episodes of severe swelling (angioedema), especially in the skin, airway, and gastrointestinal tract.
    2. Differentiate Types of Angioedema
    • Helps distinguish hereditary angioedema from other causes of swelling, such as allergic reactions.
    3. Monitor Treatment
    • To track C1-INH levels during treatment for angioedema or related disorders.

    Preparation

    1. Fasting
    • Usually, no fasting is required.
    2. Medications
    • Inform your healthcare provider about any medications, especially those that may affect the immune system.
    3. Sample Collection
    • A blood sample is drawn from a vein, typically in your arm.
    • The procedure is quick and minimally invasive
