  2. Benedict's reagent - Wikipedia

    en.wikipedia.org/wiki/Benedict's_reagent

    Generally, Benedict's test detects the presence of aldehyde groups, alpha-hydroxy-ketones, and hemiacetals, including those that occur in certain ketoses. In example, although the ketose fructose is not strictly a reducing sugar, it is an alpha-hydroxy-ketone which results to a positive test because the base component of Benedict converts it ...

  3. Reference range - Wikipedia

    en.wikipedia.org/wiki/Reference_range

    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.

  4. Normality test - Wikipedia

    en.wikipedia.org/wiki/Normality_test

    Simple back-of-the-envelope test takes the sample maximum and minimum and computes their z-score, or more properly t-statistic (number of sample standard deviations that a sample is above or below the sample mean), and compares it to the 68–95–99.7 rule: if one has a 3σ event (properly, a 3s event) and substantially fewer than 300 samples, or a 4s event and substantially fewer than 15,000 ...

  5. Reducing sugar - Wikipedia

    en.wikipedia.org/wiki/Reducing_sugar

    Reducing disaccharides like lactose and maltose have only one of their two anomeric carbons involved in the glycosidic bond, while the other is free and can convert to an open-chain form with an aldehyde group. The aldehyde functional group allows the sugar to act as a reducing agent, for example, in the Tollens' test or Benedict's test.

    The normal distribution is NOT assumed nor required in the calculation of control limits. Thus making the IndX/mR chart a very robust tool. This is demonstrated by Wheeler using real-world data [4], [5] and for a number of highly non-normal probability distributions. [6]

    For a healthy heart, the best breakfast is one that provides 20% to 30% of daily calorie intake, while wating either less or more may increase certain cardiometabolic risk factors in older adults.

  9. Lactase persistence - Wikipedia

    en.wikipedia.org/wiki/Lactase_persistence

    Lactose solution is then given to the subjects to drink, and blood glucose levels are checked at 20 minute intervals for an hour. The subjects who show a substantial rise in their blood glucose level are considered lactose tolerant. [22] A hydrogen breath test is often used to detect lactose intolerance. [citation needed]
