Question 1

Chemistry analyzers can measure the concentration of various analytes using the…

Answer 1

absorption spectrum

Question 2

T/F Different analytes absorb and reflect different wavelengths of light in a pattern that typical of that substance

Answer 2

true

Question 3

Spectrophotometry

Answer 3

Instrument directs a beam of light through a solution & measures the amount of light absorbed

The difference between the incident and transmitted light is the absorbance

Question 4

concentration of substances can be calculated from absorbance using…

Answer 4

Beer’s Law

Question 5

Reflectance photometry

Answer 5

Used in “dry chemistry” systems

Common w/ “in-house” analyzers

Question 6

tests beyond the chemistry panel

Answer 6

Urinalysis

Endocrine testing
‒ Adrenal disease
‒ Thyroid disease
‒ Pituitary disease

Digestion and absorption testing

Pancreas

Question 7

Goal of systems approach to chemistry panel

Answer 7

Identify the organ(s) involved

Create a differential list
‒ Don’t forget the CBC!

Consider additional tests
