摘要： A machine readable form for indicating one or a plurality of selections among a group of options presented on the form. A form member, preferably paper, has printed thereon a plurality of options. Each option has associated therewith a printed machine readable code, for example a bar code. Each machine readable code is initially blocked from the machine scanner by a removable cover such as a removable opaque label. When one or more of the options is selected, the associated covers are manually removed from the chosen codes only. When the entire form is scanned, the machine will be able to read and record only those codes which have been exposed by removal of the cover previously situated over those particular codes. Forms utilizing the disclosed invention provide an increased degree of accuracy in reading and recording preprinted selections on forms.

摘要： Phospho-vanillin reagent suitable for reaction with a mixture of sulfuric acid and an animal fluid containing at least 1 mg/ml lipids to determine total lipid concentration in the animal fluid comprising an aqueous solution containing vanillin and phosphoric acid having a vanillin to phosphoric acid mole ratio between 1.12 .times. 10.sup.-.sup.3 and 2.08 .times. 10.sup.-.sup.3. A sample of the animal fluid is mixed with concentrated sulfuric acid in a container, incubated, and the phospho-vanillin reagent is added to the mixture in the same container to form a chromogen. The light absorbance of the chromogen is measured and the total lipid concentration is determined in accordance with Beer's law from a standard curve relating total lipid concentration as a function of light absorbance by the chromogen.
