| Ranke's formula | A = grams of albumin per liter of a serous fluid: then, A = (sp. Gr. -1000) × 0.52 -5.406. (05 Mar 2000) |

| rational formula | In chemistry, a formula that indicates the constitution as well as the composition of a substance. (05 Mar 2000) |
| genomic formula | <molecular biology> The method used to identify the number of sets of chromosomes within a cell or organism (i.e. Its ploidy). Each set is designated n so one set is n is haploid, two sets is 2n is diploid, three sets is 3n is triploid, four sets is 4n is tetraploid, etc. Also, 2n+1 is known as trisomy (i.e. Two full sets plus a third copy of one of the chromosomes). (09 Oct 1997) |
| vertebral formula | A formula indicating the number of vertebrae in each segment of the spinal column; for man it is C. 7, T. 12, L. 5, S. 5, Co. 4 = 33, the letters standing for cervical, thoracic, lumbar, sacral, and coccygeal. (05 Mar 2000) |
| Meeh-Dubois formula | A formula for predicting surface area, assuming that it is proportional to the 2/3 power of the body weight. Synonym: Meeh formula. (05 Mar 2000) |
| Meeh formula | A formula for predicting surface area, assuming that it is proportional to the 2/3 power of the body weight. Synonym: Meeh formula. (05 Mar 2000) |
| Reuss' formula | A means of estimating the approximate amount of albumin in a transudate or exudate; 3/8 (sp. Gr. -1.000) -2.8 results in a value that is a practicable indication of the percentage of albumin in the fluid. (05 Mar 2000) |
| Gorlin formula | A formula for calculating the area of the orifice of a cardiac valve, based on flow across the valve and the mean pressures in the chambers on either side of the valve. (05 Mar 2000) |
| chemical formula | <chemistry> A represention of the elemental composition of a species, subscripts are used to indicate the relative numbers of atoms of each kind of element present. (09 Oct 1997) |
| graphic formula | A formula in which the connections of the atoms and groups of atoms, as well as their kind and number, are indicated. Synonym: constitutional formula, graphic formula. (05 Mar 2000) |
| Christison's formula | A formula to determine the number of grams of urinary solids per liter, obtained by multiplying 2.33 by the last two figures of the specific gravity of the urine. Synonym: Christison's formula, Trapp's formula, Trapp-Haser formula. (05 Mar 2000) |
| Runeberg's formula | A formula for estimating the percentage of albumin in a serous fluid, similar to Reuss' formula except that, instead of 2.8, 2.73 is subtracted in the instance of a transudate, and 2.88 in that of an inflammatory exudate. (05 Mar 2000) |
| molecular formula | In chemistry, a formula indicating the kind and number of atoms in the molecules of a substance, or its composition, but not the relation of the atoms to each other or the intimate structure of the molecule. Synonym: molecular formula. (05 Mar 2000) |
| Pignet's formula | See: Black's formula. (05 Mar 2000) |
| constitutional formula | A formula in which the connections of the atoms and groups of atoms, as well as their kind and number, are indicated. Synonym: constitutional formula, graphic formula. (05 Mar 2000) |
