Specifications
Coombs (Anti-IgG+C3d) Card (Microcolumn gel Immunoassay)

Common Name

Coombs (Anti-IgG+C3d) Card (Microcolumn gel Immunoassay)

Package

60 cards/box, 6 microtubes/card.

Intended Use

The testing card can be used for blood cross-matching and identification of unexpected antibodies. It is used for in vitro clinical diagnostic only, not for blood screening.

Introduction

Unexpected antibodies refer to the blood group antibodies other than ABO blood group antibodies (other than Anti-A, Anti-B and Anti-AB). Normally there's no unexpected antibodies in the blood. Pregnancy or repeated blood transfusions may cause the production of red blood cell isobodies. The detection rate of unexpected antibodies in general population is only 0.3%-2%. But it is the main reason for delayed immune reactions. If a patient with positive antibody is transfused with red blood cells containing corresponding antigens, hemolytic reaction will happen, leading to hemolysis or invalid transfusion.
Cross-matching test is the important basis to decide whether blood transfusion can be conducted. Cross-matching falls into two categories: major cross-match and minor cross-match. Major cross-matching: Recipient plasma is tested against donor's red blood cells to determine if the recipient has preformed antibodies against any antigens on the donor's red blood cells. Minor cross-matching: Donor plasma is tested against recipient's red blood cells to determine if the donor has preformed antibodies against any antigens on the recipient's red blood cells. The donor's blood can only be transfused to the recipient when neither of the 2 categories show hemolysis or agglutination result.
Blood cross-matching and antibody screening can help avoid hemolytic transfusion reaction caused by transfusing to weakly positive blood recipients the red blood cells containing corresponding antigens, thus improving blood transfusion safety.
Common laboratory testing methods include the classical test tube method, microtube gel method and polybrene method, etc.

Principle

The principle of the test is based on the gel technique for detecting red blood cell agglutination reactions. The agglutination occurs when the red blood cell antigens contact the corresponding antibodies, present in the reagent or in the serum or plasma sample. Each column contains polymerized dextran microspheres in buffered medium which act as a filter.
When red blood cells sensitized by IgG antibody and/or complement C₃d pass through polyspecific antihuman globulin (Anti-IgG+C₃d) gel, the red blood cells cannot get through the gel particle clearance under centrifugal force, but stay on the upper gel layer or distribute in the gel, so positive reaction occurs; when red blood cells with no sensitization by IgG antibody or compliment C₃d pass through polyspecific antihuman globulin (Anti-IgG+C₃d) gel, the red blood cells get through the gel particle clearance under centrifugal force, deposit to the bottom of microcolumn agglutination microtube, so negative reaction occurs.

Composition

Sephadex
Antihuman globulin reagent (Anti-IgG+C₃d): British Millipore; the cell strain is BRIC-8.
Preservative: <0.1% NaN₃

Storage and Validity

The testing card is stable up to the expiry date stated on the label, with the seal intact and stored at 2-25°C. Do not store near any heat, air conditioning sources or ventilation outlets, avoid direct sunlight. The validity period is 12 months after the verification.

Further materials required

Pipettes.
Disposable pipette tips.
Glass tubes.
Physiological saline solution.
LB-3000 Medical Centrifuge produced by Wuxi Yuanbo Biotechnology Co., Ltd.
LB-C02-1 Reagent Cards Incubator produced by Wuxi Yuanbo Biotechnology Co., Ltd.
Reagent Red Blood Cells for Irregular Antibody Screening.

Samples

Preferably, blood samples should be drawn into EDTA anticoagulant.
If necessary, samples stored at room temperature can be used up to 24 hours after their extraction; or at 2-8ºC, up to 48 hours.
The plasma sample should be well cleared by centrifugation at 3000r/min for 1 minute to remove fibrin, which may interfere with the reaction pattern.
If red blood cells from the bag segment are used, it is recommended to wash them with physiological saline solution before preparing the suspension.
Do not use haemolysed, cloudy or contaminated samples or with clot presence.
