Guías de pruebas respaldadas por fuentes: para qué sirve cada prueba, cómo se realiza, sus limitaciones y qué productos revisados la cubren. Las preguntas de salud personal se responden con conocimiento y orientación de preparación, no con ventas de proveedores.
IgM Expression Measurement
The determination of cellular IgM expression in a biological specimen.
Macrocyte Count
The determination of the number of macrocytes in a blood sample.
Clostridium difficile Measurement
The determination of the amount of Clostridium difficile species in a biological sample.
Beta-1 Globulin to Total Protein Ratio Measurement
The determination of the ratio of the beta-1 globulin to albumin in a biological specimen.
HIV-1 HIV-2 Antibody Measurement
The determination of the antibody reaction of a sample to the HIV-1 or HIV-2 virus.
Leukotriene B4 Measurement
The determination of the amount of the leukotriene B4 in a sample.
Alpha Glucuronidase Measurement
The determination of the amount of alpha glucuronidase present in a sample.
Hepatocyte Growth Factor Measurement
The determination of the amount of hepatocyte growth factor in a biological sample.
Herpes Simplex Virus 1/2 IgM Antibody Measurement
The determination of the amount of Herpes Simplex virus 1/2 IgM antibody present in a sample.
Two-Stage Clotting Factor Assay
A two-staged test with purified coagulation factors in the first stage, and a FXa-specific chromogenic substrate in the second stage. In the first stage, diluted sample plasma, which has been treated with Al(OH)3 to remove prothrombin, is mixed with a combined reagent (human serum, factor V, phospholipids and calcium). In the second stage, a subsample from the first stage is mixed with normal plasma, providing prothrombin and fibrinogen, and the clotting time is measured to deduce the amount of FVIII present.
Vanillylmandelic Acid to Creatinine Ratio Measurement
The determination of the ratio of vanillylmandelic acid compared to creatinine present in a sample. The measurement may be expressed as a ratio or percentage.
Growth Differentiation Factor 15 Measurement
The determination of the amount of growth differentiation factor 15 present in a sample.
Heat Shock Protein 70 Measurement
The determination of the amount of heat shock protein 70 present in a sample.
Brivaracetam Measurement
The determination of the amount of the brivaracetam in a sample.
Achromobacter denitrificans Measurement
A measurement of Achromobacter denitrificans in a sample.
Binding Antidrug IgG/IgM Antibody Measurement
The determination of the antidrug binding IgG and/or IgM antibody in a biospecimen.
Aspartate Aminotransferase Isoenzyme M Measurement
The determination of the amount of aspartate aminotransferase isoenzyme M present in a sample.
Dietary Vitamin A Measurement
A determination of the total vitamin A in a nutritional product or meal, or a portion thereof.
Skin-Homing Cytotoxic Central Memory T-Lymphocyte Count
The determination of the skin-homing cytotoxic central memory T-lymphocytes present in a sample.
Neutrophil Band Form to Total Cell Ratio Measurement
A relative measurement (ratio or percentage) of the neutrophil band form cells to total cells present in a sample. The measurement by be expressed as a ratio or percentage.
CH50 Measurement
A measurement of the complement required to lyse 50 percent of red blood cells in a biological specimen.
Interleukin 2 Receptor Subunit Beta Measurement
The determination of the amount of interleukin 2 receptor subunit beta present in a sample.
Abnormal Cells to Leukocytes Ratio Measurement
The determination of the ratio of abnormal cells compared to leukocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Coccidioides immitis Antibody Measurement
The determination of the amount of Coccidioides immitis antibody present in a sample.
