Hybrid capture assay group presentation Flashcards
The hybrid capture assay was first introduced to HPV testing by
Digene corporation
The second generation hybrid capture assay was launched in
1997 is known to yield faster results than the Branched DNA assay
The founder of Digene Corporation is
Floyd taub and was instrumental in building one of the first molecular instruments that allowed for the analysis of mutations of cancer in DNA that was inexpensive, routine, and accurate.
Floyd taub graduated from
and was the CEO of
Northwestern university and was the CEO of cytocore
Floyd taub was the founder of
Dovetail technologies
Interpretations
The detection of the substrate aka Alkaline phosphatase can be measured from a
Luminometer which is a photometer that can detect significantly low levels of light that is given off from the substrate
Interpretations
The units that are used are
Relative light units and for example if a specific sequence of DNA is HPV positive then that would mean the relative light units is over 1.0 which equals 1 pg of HPV DNA per mL.
Interpretation
Some benefits of using a luminometer are
great sensitivity, low cost, and low background interferences.
Interpretation
The hybrid capture assays allows for the interpretation of not only HPV but of
Chlamydia, Gonorrhea, CMV, and Hepatitis B
Calibration
The hybrid capture assay requires calibration with every
Run
Calibration
Must have a positive and negative
Calibrator
Calibration
Positive calibrator
Furthermore, a positive calibrator control must be used and have a coefficient of variation of 15% or less
Calibration
Negative calibrator
negative control that is less than 250 RLU and have a coefficient of variation of less the 25%
