Q

What are the three things we need to be cautious about when using EDTA in terms of blood values?

A
  1. more K
  2. chelate divalent ions- Ca & Mg and effect enzymes (ALP, CK, glucose, amylase, lipase)
  3. acidosis (bicarbonate low)

dog and cats- 7-10 platelets/100x hpf

20
Q

IF a horse of ruminant has pale-yellow plasma, what does that indicate?

normal- from caretenoids in diet

21
Q

What is it?

A

reactive lymphocyte

22
Q

With lipemia, what values are affect?

A

decrease electrolytes

increased Hb

23
Q

What is the formula for Hct? What can falsely decrease it?

A

Hct= MCV x RBC conc/10

autoagglutination

24

A

Hb/PCV x 100= g/dL

25
Q

What are the things that could cause hyperchromasia?

A

ALWAYS ARTIFACT

hemolysis of sample

interference of Hb measure (lipemia, Heinz body, extreme WBC elevation)

26
Q

Will we see reticulocytosis in horses?

A

no

27
Q

Formula for absolute reticulocyte count?

A

RBC ct/uL x uncorrected reticulocyte ct in decimal

28
Q

FOrmular for corrected reticulocyte percent?

A

PCV/mean norm. PCV for species x uncorrected reticulocyte ct in %= %

what are three things that can affect my PCV acutely?

A

splenic cx

autotransfusion (slower)

administration of fluids

31
Q

How can you tell the difference between intravascular and extravascular hemolysis?

A

intravascular- Hbnemia/uria (haptoglobin overwhelmed)

32
Q

For hemolysis, what is the order of things you will see w/ bilirubin
