DMD Frequent Questions
Frequently Asked Questions for the Diagnostic Manufacturing Division
If you work for an American Red Cross Immunohematology Reference Lab (IRL) or National Testing Lab (NTL) you are an “internal” customer. Any other customer is considered “external.”
American Red Cross IRLs or NTLs order their products directly from DMD via DMDOrders@redcross.org. External customers must order products via our distributor, Hemo bioscience, Inc.
Hemo bioscience, Inc. offers a more comprehensive product line to make your ordering easier.
- Products are shipping to internal IRL and NTL customers Monday through Thursday via overnight delivery. Arrangements can be made to schedule your preferred delivery date.
- External customers should check with Hemo bioscience, Inc. for details on their shipping arrangements.
No, they are produced from pools of donor antibody plasma, making them polyclonal reagents.
Storage requirements are listed on the label and in the Directions for Use.
- Our red cell products will have ~6 weeks until the expiration date from the date of shipping
- Blood grouping reagents will have at least 4 weeks until expiration for internal customers, and 6 months until expiration for external customers ordering through Hemo bioscience, Inc.
Human plasma is composed of many proteins. They are sometimes more visible from one reagent to another.
Some antibody specificities require adsorption with red blood cells to remove unwanted antibodies (eg. Anti-A, Anti-B, Anti-D). During this process some hemolysis occurs, which colors the serum. Depending on the number of adsorptions required, the color may be darker or lighter. The color does not affect the antigen-antibody reaction.
