Abstract: A computer-based method for automatically determining total body albumin of a living being based on the calculated intravascular albumin, the calculated observed ratio of amount of albumin in the intravascular system to amount of albumin in the extravascular system at the first time, and the baseline of expected ratio of amount of albumin in the intravascular system to amount of albumin in the extravascular system at the first time.

Abstract: Method of optimization of blood and system for customizing blood for future use of an individual which includes: obtaining a unique blood volume measurement from the individual or a potential blood donor; administering an epoetin alfa medication to the individual or potential blood donor for stimulating bone marrow to increase production of red blood cells in accordance with information obtained from the measurement of the blood volume of the individual or the potential blood donor; and storage of blood obtained from the individual or potential blood donor if the blood donor is qualified in accordance with acceptable medical procedures to donate blood.

Abstract: A disposable single-use kit for administering a precise dose of radioactive tracer to a subject with an accuracy of at least 99.9% by weight. The kit comprises a syringe, pre-filled with a known quantity of a radioactive tracer as injectate. The back of a small-bore needle is affixed to the syringe front. The front of a removable plastic needle cover incorporates airtight means for creating and maintaining an airlock in the needle front, thereby to prevent any contact between the tracer and the cover and so preclude any loss of tracer upon removal of the cover from the needle. A valve normally seals the syringe back, the valve including actuatable means for enabling a fluid flow into the syringe back, both for pre-filling of the syringe with injectate and for flushing of the injectate from the syringe into the subject.

Abstract: A multi-point method of determining a time-zero blood volume by the tracer dilution technique. A tracer is injected into the blood stream of a living being, and a plurality of mixed samples of blood and tracer are removed from the blood stream at a corresponding plurality of measured time intervals subsequent to the injecting step. A blood portion volume corresponding to each time interval is automatically determined from the tracer level in the mixed samples, and a time-zero blood portion volume is automatically calculated from the determined blood portion volumes and time intervals.
