Testing Knowledge
Test Directory
Source-backed test guides: what each test is for, how it is performed, its limitations, and which reviewed products serve it. Personal health questions are answered with knowledge and preparation guidance — not supplier sales.

The determination of the ratio of the squamous epithelial cells compared to the total cells present in a sample. The measurement may be expressed as a ratio or percentage.
Type 3 Innate Lymphoid Cell Subpopulation to Innate Lymphoid Cell Ratio Measurement
The determination of the ratio of a sub-population of type 3 innate lymphoid cells to total innate lymphoid cells present in a sample. The measurement may be expressed as a ratio or percentage.
Immature Neutrophils to Leukocytes Ratio Measurement
The determination of the ratio of immature neutrophils compared to total leukocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Matrix Metalloproteinase 10 Measurement
The determination of the matrix metalloproteinase 10 present in a sample.
Benzene Measurement
The determination of the amount of benzene in a sample.
Immunoglobulin E Measurement
The determination of the amount of immunoglobulin E present in a sample.
PMS1 Homolog 2 Measurement
The determination of the amount of PMS1 homolog 2 present in a sample.
Vacuolated Neutrophil Count
The determination of the number of neutrophils containing small vacuoles present in a sample.
Dietary Capric Acid Measurement
A determination of the total 10:0 capric acid in a nutritional product or meal, or a portion thereof.
Pyocytes Measurement
The determination of the amount of pyocytes present in a sample.
Hematocrit Corrected Reticulocytes to Erythrocytes Ratio Measurement
A relative measurement (ratio or percentage) of the hematocrit corrected reticulocytes to erythrocytes present in a sample.
Soluble B Cell Maturation Antigen Measurement
The determination of the amount of soluble B cell maturation antigen present in a sample.
Gut-Homing Helper 1 T-Lymphocyte to Helper 1 T-Lymphocyte Ratio Measurement
The determination of the ratio of gut-homing helper 1 T-lymphocytes to total helper 1 T-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
PCA3 mRNA to PSA mRNA Ratio Measurement
The determination of the ratio of prostate cancer antigen 3 mRNA as compared to the total prostate specific antigen mRNA present in a sample. The measurement may be expressed as a ratio or percentage.
Histone 2A Antibody Measurement
The determination of the amount of histone 2a antibody present in a sample.
Synoviocytes to Leukocytes Ratio Measurement
The determination of the ratio of synoviocytes to leukocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Uranium-235 Measurement
The determination of the amount of uranium-235 in a sample.
Immature Basophil Count
The determination of the amount of immature basophils present in a sample.
Reptilase Activity Actual to Control Ratio Measurement
The determination of the ratio of the biological activity of reptilase dependent coagulation in a subject's specimen when compared to the same activity in a control specimen. The measurement may be expressed as a ratio or percentage.
Eosinophils to Total Cell Ratio Measurement
The determination of the ratio of eosinophils compared to total cells present in a sample. The measurement may be expressed as a ratio or percentage.
Di-Desmethylcitalopram Measurement
The determination of the amount of di-desmethylcitalopram in a sample.
Ultra High Sensitivity C-Reactive Protein Measurement
The determination of the amount of C-reactive protein (CRP) present in a sample, usually serum from a blood draw from a subject that does not have a chronic inflammatory condition, through the use of an enhanced particle-enhanced immunoturbidimetric assay. This test is optimized to measure lower concentrations of CRP than a conventional CRP test. Accuracy is enhanced to ultra high levels through the use of a proprietary set of calibrated CRP samples.
Adenovirus Antibody Measurement
The determination of the amount of adenovirus antibody present in a sample.
Monkeypox Virus Measurement
The determination of the amount of Monkeypox virus present in a sample.
