Embodiments relate to providing one or more recommended biological reagents in response to receiving a biological reagent order. An exemplary embodiment includes identifying biological reagents based on a biological reagent order that has been received. Characteristic data of the identified biological reagents may then be evaluated to identify a characteristic conflict among the identified biological reagents. Similarly, inventory data of the identified biological reagents may then be evaluated to identify an inventory conflict among the identified biological reagents. If a conflict, either characteristic or inventory, is identified, a recommendation for an alternative biological reagent may be provided that is free from conflict. Additionally, historical use data may be maintained and referenced to aid in identifying a biological reagent as either a potential biological reagent based on a suspected biological condition or as a substitute biological reagent.
