Negative Control Serum
RH Control Serum - 200
When cell suspensions from people with serum protein abnormalities or strongly positive direct antiglobulin tests are tested against Lorne IgG Rh Blood Grouping Reagents they may produce false positive reactions. This is due to the fact that these reagents are formulated with potentiators and contain high protein levels to enable the IgG antibodies to react in direct agglutination tests. The use of Rh-Hr Control Serum enables such false positive results to be recognised. A positive result with Rh-Hr Control Serum invalidates the results obtained with these Rh Grouping Reagents.
A positive result obtained with Rh-Hr Control Serum in addition to those obtained with Lorne IgG Rh Grouping Reagents indicates that the specimen is most likely reacting with components of the reagent antisera other than the antibodies. A negative reaction with this control offers assurance that the positive results obtained with Rh grouping sera are due to specific antigen-antibody interactions
Lorne Rh-Hr Control Serum is formulated with the same levels of potentiators and protein as Lorne Human Rh Grouping Reagents with the blood group antibodies omitted. The reagent is supplied at optimal dilution for use with all the recommended techniques stated below without the need for further dilution or addition.

Anti Jka - 323
The Jka and Jkb antigens were reported in 1951 and 1953 respectively. Anti-Jka and anti-Jkb can both show dosage and are notorious for their evanescence: antibody titres that rise after stimulation but quickly drop, often to undetectable levels. Kidd system antibodies have been implicated in delayed and immediate Haemolytic Transfusion Reactions and Haemolytic Disease of the Newborn.
Toxoplasmosis Latex Test Kit - 033
When used by the recommended techniques, latex particles in the reagent will agglutinate (clump) in the presence of Toxoplasma gondii antibodies. No agglutination generally indicates absence of the Toxoplasma antibody
Coombs Control Cells - 970
In 1945, Coombs, Mourant and Race described the use of anti-human globulin serum for detection of red cell-bound non-agglutinating antibodies and the antiglobulin (Coombs) test was rapidly applied. One cause of false negative antiglobulin tests is improper washing of the cells which results in free globulin molecules being present with supposedly washed cells and these globulins neutralise the antiglobulin serum when it is added. A negative result in an antiglobulin test should only occur when anti-human globulin is added to red cells that are not sensitised. To show that test cells were properly washed and that no neutralisation has occurred, antibody-coated cells are used as a positive indicator.
Anti CW Silde - 216
Levine and Stetson discovered the Rh blood group system in 1940. Apart from D the other major Rh antigens are C, E, c and e. The D antigen is highly immunogenic and the C and e antigens are less immunogenic than E and c. The Cw antigen is one of the more rare antigens, but Anti-Cw is a fairly commonly encountered antibody. All the Rh antibodies are clinically significant since they may cause both Transfusion Reactions and Haemolytic Disease of the Newborn.
Polyspecific A.H.G Elite (Clear) - 415
In 1945, Coombs, Mourant and Race described the use of anti-human globulin serum for detecting red cell-bound non-agglutinating antibodies. In 1957, Dacie et al showed that the antibodies present in antiglobulin sera were directed against certain components of complement. Anti-human globulin reagents detect non-agglutinating antibody molecules as well as molecules of complement attached to red cells following in vivo or in vitro antigen-antibody reactions.
