Microbiology testing is important in diagnosing and treating diseases in patients based upon the presence of one or more microorganisms. Molecular testing is important in predicting, diagnosing, and treating diseases or disabilities related to changes in cells at the molecular level. What happens when the two cross? How can laboratorians manage testing and diagnosis when they overlap? These are becoming important questions for labs that seek to provide the best care for patients while managing resources efficiently.
Focus on microbiology testing
Microbiology testing is centered on the identification of microorganisms such as pathogens, molds, bacteria, and yeast. Each of these can cause serious health issues in humans. Some are allergens; others cause severe infection or failure of major organs, and can lead to serious illness or death.
Microscopic organisms can be single-cell, a cell colony, or acellular. Microbiology testing can include virology, mycology, parasitology, and bacteriology. Pathogens can be from external sources such as the environment, other people, or animals, or they can be from internal sources (host-based).
