Pappalysin-1, also known as pregnancy-associated plasma protein A, and insulin-like growth factor binding protein-4 protease is a protein encoded by the PAPPA gene in humans. [1]
In statistical process control (SPC), the ¯ and R chart is a type of scheme, popularly known as control chart, used to monitor the mean and range of a normally distributed variables simultaneously, when samples are collected at regular intervals from a business or industrial process. [1]
The intent is to demonstrate that critical processes have stable variability and that is running near the intended nominal value. Qualified Laboratory Documentation Copy of all laboratory certifications (e.g. A2LA, TS, NABL) of the laboratories that performed the tests reported on section 10.

The "chart" actually consists of a pair of charts: one, the individuals chart, displays the individual measured values; the other, the moving range chart, displays the difference from one point to the next.
Values for other compounds may be found in a variety of available reviews and monographs.

When Dr. Oz sat Rachael Ray down for a blood pressure test during a segment of her show, he wasn't entirely pleased with the numbers he saw. In fact, he made her do it again -- and he called her ...
The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
