Body Fluid Dilution

Quality patient care is a goal of all medical laboratory scientists. Accurate and precise methods and procedures are required to achieve the goal in laboratory testing. Most of the methods are characterized by an analytic measurement range (AMR) for all analytes (e.g., carbohydrates, glucose, hormones, lipids, electrolytes, etc.). Often the body fluid (BF) analyte concentration may exceed the range. For example, the glucose method AMR or range of linearity is 0 – 450 mg/dl, while an unknown glucose of 500 mg/dl would be above the range. In this situation, a dilution is needed to obtain the correct glucose results. Your challenge is to make various dilutions that meet the stated specifications.
