Microbes & Organisms

How does Arkstone detect the microbes or resistance genes in each specimen?
The detection of microbes in a specimen is determined by the laboratory. Arkstone does not analyze the actual specimen. The laboratory also determines the t...

Why are so many microbes detected in a specimen?
Molecular diagnostics, such as PCR and NGS, can detect microbes by analyzing molecular components of the microorganism (DNA, RNA, proteins etc.). Since this...

Can I use molecular diagnostics for the McGeer Criteria?
The McGeer Criteria uses CFU per ml or colony-forming units per milliliter. This relies on culture and stains in order to calculate the number of viable bac...

What if a microbe is detected by one testing modality but not the other?
Cultures and molecular diagnostics provide similar information, such as organisms detected in a sample. However, the technology behind each method is differ...
