Rapidvet-h Companion Animal Major Crossmatch Test KitThis treatment applies to the following species:
(donor Blood / recipient Serum)
For Use On Either Canine Or Feline Species
Description And Intended UseCrossmatch identifies serological incompatibility between a donor and recipient. Performing a crossmatch is an essential procedure to be considered before most transfusions and in addition to blood typing. Crossmatch reveals incompatibilities between a donor and recipient that will not be evident from blood typing alone.
Rapidvet-h Major Crossmatch Is Performed Using Donor Red Blood Cells And Recipient Serum. Plasma Should Not Be Used With This Test. The Test Will Alert The Veterinarian To The Existence Of Antigens On Donor Red Blood Cells That Correspond To Antibodies, Whether Acquired Or Naturally Occurring, Present In The Recipient Serum. In An Incompatible Transfusion, These Antibodies Can Cause A Major, Life-threatening Reaction.
in Dogs, If It Can Be Determined With Certainty That There Has Been No Prior Transfusion, A Crossmatch Need Not Be Done. It Is Necessary To Determine Whether The Dog Is Dea 1.1 Positive Or Negative. Tests For Determining Whether There Are Also Antigens On The Red Cells For Dea 4, 5, 7 Or 9 Are Not Commercially Available. New Canine Blood Types Are Being Discovered Frequently, Including Dal And Others. There Are No Commercially Available Tests For These Either.
if Blood Is Used That Is Incompatible With Any Of These Types (x+ Blood Transfused Into An X- Dog) In Even The First Transfusion, The Viability Of The Transfused Cells Will Decline Rapidly, A Second Transfusion May Be Required Within 4 To 5 Days, And By Then Antibodies To The Incompatible Antigen Will Have Formed.
if A Second Transfusion Is Ever Needed, Determining Only That The Blood Of That Donor And The Recipient Is Dea 1.1 Compatible Will not Be Sufficient. Antibodies In The Recipient’s Serum To Any Other Antigens On The Red Cell Of The Original Donor May Have Formed. Only A Crossmatch Will Determine If That Has Occurred.
cats Have Naturally Occurring Antibodies To Antigens Not On Their Red Cells. Thus Cats With Type A Blood Have Antibodies To Type B Antigens And Cats With Type B Blood Have Antibodies To Type A Antigens. In This Species, A Crossmatch Should Be Performed Prior To every Transfusion. New Feline Red Blood Cell Antigens Are Being Discovered, Including mik And Others. Cats Lacking mik Antigens On Their Red Cells Will Have mik Antibodies Before any Transfusion. Thus Determining Only The A Or B Blood Type For Compatibility Is Not Sufficient. Only A Crossmatch Will Uncover The Problem.

Test Procedure [follow Bracketed Numbers On Procedure Diagram]
use A Clean Pipette For every Step To Prevent Contamination.
 pipette Donor Sample: 2 Drops (0.1 Ml) Whole Blood or 1 Drop (0.05 Ml) Prbcs To Blue Top Blood Prep Tube; Cap Tightly And Invert Several Times To Mix Thoroughly. Place Upright In Test Stand.
 pipette 4 Drops (200 µl) Recipient Serum To Yellow Top Reaction (r) Tube.
from Blue Top Blood Prep Tube, Using A Clean Pipette For each Transfer
 TRANSFER 2 drops (100 µl) to Yellow Top Reaction (R) Tube. Replace cap, tighten and invert several times to mix thoroughly.
 TRANSFER 2 drops (100 µl) to Green Top Negative (-) Control Tube. Replace cap, tighten and invert several times to mix thoroughly.
 TRANSFER 2 drops (100 µl) to Red Top Positive (+) Control Tube. Replace cap, tighten and invert several times to mix thoroughly.
IncubateLet all tubes stand for five (5) minutes at room temperature (20-25°C / 68-77°F).
 TRANSFER 1 drop (50 µl) from Yellow Top Reaction (R) Tube to Clear Top Reaction (R) Gel Tube (yellow-bordered label). Cap tightly.
 TRANSFER 1 drop (50 µl) from Green Top Negative (-) Control Tube to Clear Top Negative (-) Control Gel Tube (green-bordered label). Cap tightly.
 TRANSFER 1 drop (50 µl) from Red Top Positive (+) Control Tube to Clear Top Positive (+) Control Gel Tube (red-bordered label). Cap tightly.

Interpreting And Reporting Results
Use the Crossmatch Photo Identifier provided to interpret results in Clear Top Negative (-) and Positive (+) Control Gel Tubes.
Negative ControlClear Top Negative (-) Control Gel Tube (green-bordered label) should demonstrate a collection of red blood cells at the bottom of the gel column.
Positive ControlClear Top Positive (+) Control Gel Tube (red-bordered label) should demonstrate an agglutination of red blood cells at the top of the gel column or a dispersion of red cells mid matrix and above.
Important: If Controls Do Not React As Stated Above Do Not Proceed With The Interpretation Of Test.
Crossmatch InterpretationInterpret reaction in Clear Top Reaction (R) Gel Tube (yellow-bordered label) using the Crossmatch Photo Identifier provided. Record results using report card provided.
Positive Crossmatch Indicates The Recipient Is At Risk For Demonstrating A Transfusion Reaction.
do Not Transfuse Using This Donor
Negative Crossmatch Indicates The Recipient Is Likely Not At Risk For Demonstrating A Transfusion Reaction From The Donor.
test Results Might Be Affected By The Age Of The Cells Used. Stored Blood Might Exhibit A Weaker Reaction Than That Shown In The Photo Identifier.
important Notes: Crossmatching Is Done In Addition To, And Does Not Replace, Blood Typing.
Transfusions Involving Incompatible Blood Types Will Result In The Activation Of Alloantibodies Which May Cause Life-threatening Reactions, Or The Production Of Antibodies Which May Cause Serious Complications In Subsequent Transfusions. In Addition, The Lifespan Of Incompatible Rbcs Will Be Shortened, Increasing The Need For Further Transfusions.
If Oxyglobin® Is In Recipient Blood, Or In The Event Of Severe Hemolysis, This Test Is Not Recommended.
Plasma Should Not Be Used With This Test.
StorageShelf-life: 24 months. Store at room temperature until expiration date: DO NOT FREEZE.
DisposalDispose of all biological materials, pipettes and tubes in a biohazard container.
