👉 The "blank fluid" refers to a liquid substance that is typically colorless, odorless, and tasteless, often used as a reference point in scientific and medical contexts. It serves as a baseline for measuring other fluids' properties, such as viscosity or density. In medical settings, it's commonly used to assess the consistency of bodily fluids like blood or urine, while in laboratory experiments, it helps control variables and ensure accurate results by providing a neutral medium. This fluid is crucial for maintaining consistency and reliability in various tests and procedures.
