Term
What signals haematopoeisis |
|
Definition
|
|
Term
Name 6 causes of renal hypoxia |
|
Definition
Reduced renal blood flow Cardiopulmonary disease Haemorrhage Hypotension High altitude Reduced Haemoglobin concentrations |
|
|
Term
How does renal hypoxia result in haematopoeisis |
|
Definition
Renal hypoxia leads to erythropoeitin production which leads to RBC production |
|
|
Term
What are the three main definitions of anaemia |
|
Definition
Reduced RBC mass Reduced RBC volume Reduced haemoglobin concentration |
|
|
Term
What are the 3 main headings by which anaemia is classified |
|
Definition
Regenerative vs non regenerative Haemolytic vs non haemolytic Acute vs chronic |
|
|
Term
What are some of the main clinical presentations of acute anaemia |
|
Definition
Weakness Syncope Tachycardia Weak pulse Exercise intolerance Tachypnoea Dyspnoea Haemic murmur |
|
|
Term
What is a haemic murmur? What causes it? |
|
Definition
Reduced viscosity of the blood |
|
|
Term
What are some of the main clinical presentations of chronic anaemia |
|
Definition
The same as acute anaemia except the animal may tolerate it more Weakness Syncope Tachycardia Weak pulse Exercise intolerance Tachypnoea Dyspnoea Haemic murmur |
|
|
Term
What are the 4 main tests used in investigating anaemia |
|
Definition
Haematology Biochemistry Urinanalysis Faecal analysis |
|
|
Term
What are some of the more specific and some of the more peripheral tests that can be used to investigate anaemia |
|
Definition
Autoagglutination ACTH stimulation Diagnostic imaging Endoscopy Coomb's test Clotting profiles Bone marrow aspirates and biopsies |
|
|
Term
What type of tube would you collect blood in for haematology |
|
Definition
EDTA - orange bottle usually in Eamonn's |
|
|
Term
What are some of the crucial measurements in haematology for assessing anaemia |
|
Definition
Packed cell volume Haemoglobin RBC count platelet count Leucocyte count |
|
|
Term
What haematological test will help assess what type of anaemia you are dealing with |
|
Definition
Mean cell haemoglobin concentration Mean cell volume Mean cell haemoglobin |
|
|
Term
What are some of the main RBC morphology used to assess and diagnose anaemia |
|
Definition
Polychromasia Macrocytsis Microcytosis Hypochromasia Spherocytosis Schistocytosis Nucleated RBC |
|
|
Term
What can a reticulocyte count help evaluate |
|
Definition
Whether the anaemia is regenerative or not |
|
|
Term
What will a platelet count help evaluate |
|
Definition
Whether the anaemia is due to haemorrhage either internal or external |
|
|
Term
What does polychromasia indicate |
|
Definition
that the anaemia is regenerative |
|
|
Term
What does macrocytosis indicate |
|
Definition
it can be normal folate deficiency FeLV FIV can also indicate anaemia is regenerative |
|
|
Term
What does microcytosis indicate |
|
Definition
can be normal erythrocytosis (high RBC) portosystemic shunt |
|
|
Term
What does hypochromasia indicate |
|
Definition
|
|
Term
What does sphereocytosis indicate |
|
Definition
|
|
Term
|
Definition
when the RBC are not biconcave |
|
|
Term
|
Definition
When parts of the cells are cleaved off |
|
|
Term
What does schistocytosis indicate |
|
Definition
That there is turbulence in the blood vessels Could be caused by DIC Haemangiosarcoma |
|
|
Term
What are the 3 main things and the 4 lesser things examined in Biochemistry in investigating anaemia |
|
Definition
Main Urea, bilirubin, albumin Lesser Hyperkalaemia, hypercalcaemia, hyponatraemia, hypercholestrolaemia |
|
|
Term
What does elevated urea and creatinine mean in anaemia |
|
Definition
renal failure leading to lack of erythropoeitin production |
|
|
Term
What does elevated urea with no renal failure mean in anaemia |
|
Definition
blood loss in the upper GIT May be regen but becoming non regen |
|
|
Term
What does bilirubin indicate |
|
Definition
|
|
Term
What can albumin be used to determine in anaemia |
|
Definition
acute haemorrhage vs chronic and haemolytic Decreased in acute haemorrhage but normal otherwise |
|
|
Term
Hyperkalaemia can indicate what in anaemia |
|
Definition
|
|
Term
Hyponatraemia can indicate what in anaemia |
|
Definition
|
|
Term

|
Definition
|
|
Term
What can hypercalcaemia indicate in anaemia |
|
Definition
|
|
Term

|
Definition
|
|
Term
What are the 3 main things looked at in urinanalysis |
|
Definition
Specific gravity Haemoglobinuria Haematouria |
|
|
Term
What can urine specific gravity indicate in anaemia |
|
Definition
Renal failure if it is low meaning decreased erythropoeitin production |
|
|
Term
|
Definition
When haemoglobin is found in the urine indicating haemolysis and the entire urine is red with no settling |
|
|
Term
What does haemoglobinuria indicate |
|
Definition
|
|
Term
|
Definition
When red blood cells are present in the urine which indicates renal haemorrhage and presents with the first part of the urine flow as red and it will settle in the container |
