Q

What is wet chemistry?

A
  • uses liquid reagents
  • same tip (washed)
  • cheeper
  • require good water source (filtration) and drainage

Q

What are the two types of reaction times?

A

Q

What is an example of a rate reaction?

A

Enzymatic tests

17
Q

What is the purpose of automation in urinalysis?

A
  • Eliminate the need for dipping
  • Minimal touching
18
Q

What is the biggest problem child in the lab? (electrolytes) and why?

A

LIPAFAM
Potassium #3
because easily influenced by hemolysis

19
Q

What is an alert threshold index?

A

Alerts interferences in sample which alerts to block out the top three problem child’s (LIPAFAM) which are likely false elevated.

20
Q

What is a renal function panel?

A

Urea and Creatinine

21
Q

What is an electrolyte panel?

A

Na
K
Cl

22
Q

What is a Liver function panel?

A

AST
ALT
ALP
LDH

23
Q

What is a Drug screening panel?

A

Screens for drugs (acetaminophen)

24
Q

What is a tox screen panel?

A

Multiple drugs

25
Q

What is a Lipid test panel?

A

Cholesterol
Triglycerides
LDL
HDL

26
Q

What are some considerations to take with samples?

A
  • Light sensitivity
  • Centrifugation
  • Volatiles (Ketones and ethanol)
  • Glycolytic (glucose)
  • Refrigerations (LDH = no)
  • Time elapsed (blood gases)
    -Special protocols
27
Q

What tubes are usually collected for chemistry?

A

SST or PST

some test collected in special specific tubes

28
Q

How long are samples kept for?

A

Usually a week

29
Q

What considerations are there with samples sizes requirements?

A

Dead space that must be filled.
