Complement Total (CH50) Serum EIA

• The Complement Total (CH50) Serum EIA Test is a diagnostic assay designed to measure the activity of the complement system, an integral part of the immune response
• This Complement Total (CH50) Serum EIA Test evaluates the ability of the complement system to lyse target cells, providing an overview of its functionality
• By using an enzyme immunoassay (EIA) method, this test accurately quantifies the total hemolytic complement activity in the serum, which is crucial for identifying deficiencies or abnormalities in the immune response

• Immune System Evaluation: Helps assess the overall functionality of the complement system
• Diagnosis of Complement Deficiencies: Identifies potential deficiencies in complement components that can lead to recurrent infections
• Monitoring Autoimmune Disorders: Assists in diagnosing and managing conditions like lupus and rheumatoid arthritis
• Evaluating Suspected Complement Pathway Abnormalities: Determines if there are defects in the classical or alternative complement pathways
• Post-Transplant Monitoring: Tracks the effectiveness of immunosuppressive therapies and detects potential complications

• Sample Collection: A blood sample is collected from a vein in the patient's arm. This sample is then processed to obtain serum, which is used for the Complement Total (CH50) Serum EIA Test
• Enzyme Immunoassay (EIA) Kit: The test uses a specialized EIA kit designed to measure the hemolytic activity of the complement system. This kit includes reagents, controls, and a substrate necessary for the assay
• Calibration and Controls: Standardized calibrators and controls are included to ensure the accuracy and precision of the test results. These controls help verify that the assay is working correctly
• Hemolytic Assay: The core component of the test is where the serum sample is mixed with sensitized sheep red blood cells. The extent of hemolysis (red blood cell lysis) is measured to determine the total complement activity
• Result Analysis: The test results are analyzed using a spectrophotometer or a similar device to measure the degree of hemolysis, which is then converted into CH50 units
• Interpretation Guidelines: The kit includes guidelines for interpreting the results, including normal reference ranges and the potential clinical implications of abnormal results
• Quality Assurance: Comprehensive quality assurance procedures are included to ensure the reliability and reproducibility of the test results. This includes regular calibration and maintenance of equipment, as well as adherence to standardized protocols

• Normal CH50 Levels: Indicate a fully functional complement system, suggesting no significant complement deficiencies
• Low CH50 Levels: May suggest a deficiency in one or more complement components, pointing to conditions such as hereditary angioedema, autoimmune diseases, or chronic infections
• High CH50 Levels: Can indicate acute phase responses or inflammation, reflecting an overactive complement system

• Normal Range: Typically between 41 and 90 U/mL, depending on the specific laboratory standards
• Abnormal Results: Values outside the normal range may require further investigation to identify underlying conditions or diseases affecting the complement system

Q. What is the Complement Total (CH50) Serum EIA Test?
The Complement Total (CH50) Serum EIA Test measures the activity of the complement system, which is part of the immune system that helps fight infections and clear damaged cells

Q. Why is the Complement Total (CH50) Serum EIA Test important?
This Complement Total (CH50) Serum EIA Test helps diagnose complement deficiencies, monitor autoimmune diseases, and evaluate the immune system's overall health

Q. How is the CH50 Test performed?
A blood sample is taken from a vein in your arm, and the serum is analyzed using an enzyme immunoassay to measure complement activity

Q. Do I need to prepare for the CH50 Test?
No special preparation is needed for this Complement Total (CH50) Serum EIA Test. However, inform your doctor about any medications or supplements you are taking

Q. What do normal CH50 levels mean?
Normal levels suggest that the complement system is functioning properly, indicating a healthy immune response

Q. What do low CH50 levels indicate?
Low levels may indicate a deficiency in one or more complement components, which could be due to genetic conditions, autoimmune diseases, or chronic infections

Q. Can medications affect CH50 Test results?
Yes, certain medications, particularly those affecting the immune system, can influence test results. Always inform your doctor about any drugs you are taking
