Question 1

most common cause of B12 deficiency

Answer 1

pernicious anaemia

Pernicious anaemia is the most common cause of vitamin B12 deficiency. Intrinsic factor is normally produced in the stomach and binds B12 in the gut. Autoimmune destruction of the stomach lining leads to reduced intrinsic factor production impairing B12 absorption. This can eventually precipitate a vitamin B12 deficiency and macrocytic anaemia as is the case here. B12 deficiency can also damage spinal cord myelination resulting in neurological symptoms.

Question 10

expalin iron def an readings

Answer 10

The total iron-binding capacity (TIBC) increases as the body produces more transferrin (the iron transport protein) to maximise iron uptake

ferittin reflects stores so low
iron low to depleted stores

ransferrin saturation, which is calculated as (serum iron ÷ TIBC) × 100, will be low due to the combination of low serum iron and high TIBC.
