Q

List 3 differences between acute and chronic leukemia:

A

ACUTE: predominantly IMMATURE (undifferentiated) cells in the bone marrow, rapid (weeks to months), young or older animals

CHRONIC: predominantly MATURE (differentiated) cells in the bone marrow, slow (months to years), more common in older animals

16
Q

What is the preferred tube for hematology/CBC in birds and reptiles?

a. sodium citrate
b. heparin
c. EDTA
d. serum

A

B - reptile and bird RBCs will lyse in EDTA

17
Q

What tube is preferred for coagulation panels and platelet function studies?

a. heparin
b. sodium citrate
c. EDTA
d. A and C

A

B

18
Q

What is the difference between plasma and serum?

A

PLASMA: contains anticoagulants, so it will contain clotting proteins and fibrinogen, higher calcium and less potassium

SERUM: does not contain anticoagulants, so coagulation will occur and it will not contain coagulation factors or fibrinogen; used for biochemistry and electrophoresis

19
Q

What is the order in which tubes are filled after sample collection?

A
  • blue-top sodium citrate
  • red-top serum
  • green-top heparin
  • purple-top EDTA
20
Q

List the main interferences caused by lipemia, hemolysis, and bilirubin:

A

LIPEMIA = enhances hemolysis, increases lipase, ALT, AST, LDH, glucose, CREA, bilirubin

HEMOLYSIS = increased AST, K, ALP, TP, Ca, ALB, bilirubin, ALT, CK

BILIRUBIN = decreased creatinine, increased bilirubin

21
Q

How does the collection of blood in EDTA-contaminated and citrate-contaminated tubes affect results?

A

EDTA = decreased Ca and increased K

SODIUM CITRATE = decreased Ca, no effect on K

22
Q

All of the following are true EXCEPT:

a. in mammals, it is normal for young animals having lower levels of protein than adults
b. total protein reports the albumin and globulins
c. albumin is responsible for the colloidal osmotic pressure
d. albumin is synthesized by the kidney

A

D

23
Q

Globulins are…

a. proteins of broad-ranged function
b. categorized on electrophoresis motility as alpha, beta, and gamma globulins
c. fibrinogen, prothrombin, and plasminogen are a part of the beta globulins
d. all of the above

A

D

24
Q

Select the true statement in regards to renal function.

a. loss of the ability to concentrate urine is observed after renal azotemia had taken place
b. kidney function is evaluated mainly by CBC
c. the most common test to evaluate glomerular filtration rate is the direct method
d. loss of more than 75% of the nephron function could result in azotemia

A

25
Q

Glomerular filtration rate is assessed by the following:

a. PARR
b. BUN

The following are functions of the kidney:

a. regulation of blood pressure
b. erythropoietin production
c. calcium homeostasis

A

A, B, C

28
Q

The glomerular filtration rate is evaluated with…

a. refractometer
b. CBC
c. serum
d. blood film

A

C

29
