17
Q

Clinical signs are only seen after the liver has lost how much of it’s functioning ability?

18
Q

This organ has regenerative capabilities

19
Q

Liver specific
Created by hepatocytes
Increased levels present with liver dz, trauma to the liver, and toxins

A

SGPT

AKA ALT

20
Q

Not liver specific

Synthesized in liver and cardiac and skeletal muscles

A

SGOT

AKA AST

21
Q

The byproduct of hemoglobin metabolization
Not liver specific
Increases seen with hepatic lipidosis, hemolytic anemia, hyperthyroidism, and pancreatitis

A

Billirubin (TBIL)

22
Q

Main protein of blood plasma made by liver cells
Decrease is more common than increase; decreases can be caused by heartworm dz, ehrlichia, and IBD
Levels below 1.0g/dL are dangerously low

A

Albumin (ALB)

23
Q

Pancreatic function tests include

A

AMYL, LIPA, and GLU

24
Q

Breaks down starches and glycogen in sugars
Increases can be seen with renal failure or peritonitis
Acute or chronic pancreatitis can cause this as well

A

Amylase (AMYL)

25
Q

Assists in breaking down fatty acids
Values are usually parallel to amylase values
Increases seen with pancreatitis, liver and renal dz

A

Lipase (LIPA)

26
Q

Evaluates insulin production
Blood must be centrifuged immediately because this binds to RBCs and decreases by 10% per hour
Stress can increase values
Below 60 mg/dL is dangerously low

A

Glucose (GLU)

27
Q

A patient testing for their glucose levels should fast for how long before the test?

28
Q

Plays important role in steroid production and levels are helpful in diagnosing hypothyroidism and Cushing’s dz

A

Chlesterol (CHOL)

29
Q

Used to determine the hydration levels of a patient

A

Total Protein (TP)

30
Q

NOT AN ELECTROLYTE
Most abundant MINERAL in the body
Important role in muscle contraction and blood clotting

A

Calcium (Ca)

31
Q

When combined with phosphorus, this creates the material that forms dense, hard teeth and bones

A

Calcium

Calcium phosphate

32
Q

Dietary mineral required in high amounts

Excessive amounts will accelerate the progression of renal failure

A

Phosphorus

36
Q

Maintains cellular integrity

Important in maintaining correct water balance

A

Chloride (Cl)

37
Q

Performs PT and PTT tests
Fresh or citrated whole blood
Important information about intrinsic and extrinsic clotting factors and fibrinogen

A

Coag Dx Analyzer

38
Q

PT means

A

ability to clot

39
Q

PTT

A

clotting disorder

40
