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.
Regulatory Memory B-Lymphocyte to Regulatory B-Lymphocyte Ratio Measurement
The determination of the ratio of regulatory memory B-lymphocytes to regulatory B-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Moraxella catarrhalis DNA Measurement
The determination of the amount of Moraxella catarrhalis DNA in a biological sample.
Ketone Body Measurement
The determination of the amount of ketone bodies (acetone, acetoacetic acid, beta-hydroxybutyric acid, beta-ketopentanoate and beta-hydroxypentanoate) present in a sample.
Memory Cytotoxic T-Lymphocyte to Cytotoxic T-Lymphocyte Ratio Measurement
A relative measurement (ratio) of the memory cytotoxic T-lymphocytes to cytotoxic T-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Hedgehog-Shaped Cells to Total Assessed Cells Ratio Measurement
The determination of the ratio of the hedgehog-shaped cells to total assessed cells in a sample. The measurement may be expressed as a ratio or percentage.
Helper Regulatory T-Lymphocyte to Lymphocyte Ratio Measurement
The determination of the ratio of helper regulatory T-lymphocytes to total lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Retinol Binding Protein 4 Measurement
The determination of the amount of retinol binding protein 4 in a sample.
Dietary Protein Foods Measurement
A determination of the protein-rich food in a nutritional product or meal, or a portion thereof.
Aspergillus DNA Measurement
The determination of the amount of DNA from any member of the genus Aspergillus present in a sample.
Free Immunoglobulin Light Chain Measurement
The determination of the amount of free immunoglobulin light chains present in a sample.
Ketovaline Measurement
The determination of the amount of ketovaline in a sample.
Mean Platelet Volume Measurement
The determination of the average size of the platelets present in a blood sample.
Vitamin D Measurement
The determination of the amount of vitamin D present in a sample.
Micronucleated Normochromatic Erythrocytes Count
The determination of the micronucleated normochromatic erythrocytes in a sample.
Trazodone Measurement
The determination of the trazodone in a sample.
Absolute T Lymphocyte Count
The measurement of the number T lymphocytes, which are leukocytes that express CD3, in a cubic millimeter of blood. It is calculated by multiplying 1000 by both the total leukocyte count and the percent of T cells in the differential leukocyte count.
Erythroid Cells to Nucleated Cells Ratio Measurement
The determination of the ratio of erythroid cells compared to nucleated cells present in a sample. The measurement may be expressed as a ratio or percentage.
N-Nitrosopiperidine Measurement
The determination of the amount of N-nitrosopiperidine in a sample.
Nuclear Swelling Measurement
The determination of the expansion of the nucleus of the cells in a sample.
Natural Killer Cell Subpopulation to Leukocyte Ratio Measurement
The determination of a sub-population of natural killer cells to total leukocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Neutrophilic Metamyelocyte to Total Cell Ratio Measurement
The determination of the ratio of the neutrophilic metamyelocytes to total cells in a sample. The measurement may be expressed as a ratio or percentage.
Acinetobacter calcoaceticus/baumannii Complex DNA Measurement
The determination of the amount of Acinetobacter calcoaceticus-baumannii complex DNA in a biological sample.
Monocyte Subpopulation to Total Monocytes Ratio Measurement
The determination of the ratio of a subpopulation of monocytes to monocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Alfentanil Measurement
The determination of the amount of the alfentanil in a sample.
