BLOOD TYPING

Weak D (CE Approved)

Detecting weak D antigen can prove frustrating our testing solutions make elusive results simple and clear.

Weak D

Sometimes low quantities of the D antigen on red cells can mean you might have a false D negative result. With one reagent that can be utilized for both tube and gel technologies optimize your resources for serology testing.

Molecular technology

Go beyond serological testing for your most complex cases

Enhance your ability to confirm the Rh(D) negative donors, rationalize the use of RhIG injections for pregnant women as well as the use of Rh(D) neg blood units for patients with BLOODchip ID RHD XT. Predict the RhD phenotype that cannot be resolved by serology and benefit from knowing the patient's or donor's genotype with a user-friendly streamlined workflow ready in just 4 hours and that only requires 30 minutes of hands-on time.
