Of globin, amino acids and iron, which is passed out of the body as billirubin?
In which layer would the platelets and leukocytes be found?
How do you differentiate a R.B.C from a reticulocyte?
R.B.C's do not contain RNA
Reticulocytes don't have a nucleus
Reticulocytes have more Hb
Blood samples must be mixed before testing to imitate patient blood consistency
How does the principle of cell conducting work?
R.B.C's are poor conductors of electricity, and so when passing through an aperture will stop the current
R.B.C's are excellent conductors of electricity, and so when passing through an aperture will pass a current along
Large cells leave more of a gap
Large cells show a spike in current

Large red blood cells
Small red blood cells
Unusual loss of red blood cells
What is the normal range of HGB?
Which of the following is NOT a cause of Noramcytic A's?
Acute blood loss
In N.A, the MCV is low and the HGB is normal
Why would a patient be given a bone marrow transplant instead of a transfusion in some cases of N.A's?
To replace lost blood
In the case of metastasis, to restore blood production
To prevent unusual R.B.C destruction
What are the two causes of microcytic anaemia?
Thalassaemia is a genetic abnormality that reduces iron absorption
How do you intenfidy Mi.A?

Test serum ferratin
Test serum Fe
Iron is supplied by circulating transferrin
The normal level of body iron is between 3-5g
Where is iron gained from?
Recycled red blood cells
Broken down muscle tissue
Regular transfusions can lead to iron overload
Fe deficiency can be caused by inadequate supply and...
