Disclosed are methods, materials and devices for approximation of blood volume in a fluid, such as in a biological fluid collected during a surgical procedure. The method and devices may include the use of an RBC flocculant, for example polyDADMAC, and an approximate blood hematocrit from the type of animal blood being evaluated, as well as a calculated RBC packing ratio corresponding to the collection device being used. Also provided is a Blood Indicator Panel (BIP), comprising a series of markings calculated from an observed red blood settlement volume, the average animal blood hematocrit, and a calculated RBC packing ratio “η” value for the collection device. A collection device with a BIP is disclosed. Pediatric (about 200 ml or 250 ml size container), adult human (about 1,000 ml-1,500 ml) and veterinary (about 500 ml-2,500 ml) collection containers are also disclosed, that include a RBC flocculant, for use in approximating blood volume in a fluid.
A blood measurement indicator panel comprising a front side and a back side, wherein the front side or the back side comprises a first series of markings, said first series of markings providing a measure of sedimented human red blood cells in a collection container, wherein each of the first series of markings is calibrated for an average human blood hematocrit and a human red blood cell packing ratio in the collection container.
The blood indicator panel of claim 2, wherein the collection container has a volume of about 1200 ml or about 3000 ml.
