Intro To Chem Path Flashcards
What is chemical pathology?
Chemical pathology is the study of the biochemical basis of a disease, the biochemical application and the molecular diagnostic techniques.
What are the roles of Chemical Pathology in healthcare?
- Diagnosis.
- Screening.
- Prognosis.
- Monitoring.
What is diagnosis?
Diagnosis refers to differentiating between several possibilities of a disease or ailment through using the patient’s initial history or examinations.
What is screening?
To screen for the presence of a particular disease in an otherwise healthy population.
What is Prognosis?
It refers to the prediction of disease susceptibility by observing health trends.
What is monitoring?
Refers to check a disease progression or response to treatment.
What are fluoride oxalate tubes used for?
To prevent erythrocyte glycolysis using us blood glucose
How do you prevent Bilirubin and B-carotene from photo degrading?
By putting them in aluminum foil.
Factors to consider when taking a blood sample.
- Venostasis
- Posture of patient
- Site of venipuncture
Changes that occur in the blood after collection.
- Diffusion of K+, lactase dehydrogenase, asparate transaminase through the red blood cells into the serum/plasma.
2.Decrease in glucose concentration due to erythrocyte glycolysis.
- Photo degradation of Bilirubin and B-carotene when expose to light.
What is limit of linearity?
The maximum reading ability, or the accuracy limit of a machine past which it cannot provide a value.
What is analytical sensitivity?
Refers to the ability to smallest amount or concentration of an analyte that can be detected.
What is analytical specificity?
The ability to test for a particular analyte.
What is precision?
Precision is when a set of values fall within a similar range of values.
What is accuracy?
When a value is the exact or similar to the value that is wanted.
