Q

HTC:

Hund, kat, hest = normal?

A 
Hund = 39-59%
Kat = 24-42%
Hest = 24-46%
17
Q

Relativ polycytæmi?

A

Det absolut antal erythrocyter uforandret, fylder mere relativ pga. nedsat plasmavolumen (dehydrering = htc stiger)

18
Q

Absolut polycytæmi?

A

Plasmavolumen uforandret, men erythrocyte som udgør mere i plasmavolumen.

19
Q

Lav ht = ?

A

ANÆMI

20
Q 
Plasmasøjle: 
Normal = ? 
Hyperlipæmi = ? 
Icterus = ? 
Hæmolyse = ?
A 
Normal = klar + farveløs 
Hyperlipæmi = uklar + mælkehvid
Icterus = klar + gul
Hæmolyse = klar + dødelig
21
Q

Hvad betyder?
MCV?
MCH?
MCHC?

A

MCV = middelcellevolum

MCH = middelcellehæmoglobin

MCHC = middelcellehæmoglobinkoncentration
