1
Q

A

responsbile for maintaining blood fluidity and preventing blood loss by activating rapid, localised clotting at sites of vascular damage.

Q

What is white blood cell differential in FBC?

A

Looks at types of white blood cells present.

5 types: neutrophils, lymphocytes, moocytes, eosinophils and basophils.

Q

What is haemocrit in FBC?

A

Measures the amount of space red blood cells take up in the blood.

Reported as a percentage (0 to 100) or proportion (0 to 1) .

Integral to haemostats

Aid inflammatory and immune responses. Help maintain vascular integrity
Contribute to wound healing

Q

What is mean platelet volume in FBC?

A

machine calculated measurement of the average size of your platelets.

New platelets are larger. increased MPV occurs when increased number of platelets are produced.

Q

What is MCV in FBC?

A

Mean corpuscular volume.

Measurement of average size of RBCs.

Decreased MCV = RBCs smaller than normal, may indicate iron deficiency anaemia, inflammation or sometimes thalassaemias

Q

What is MCHC in FBC?

A

Mean corpuscular haemoglobin concentration.

The concentration of Hb in RBCs

Decreased seen where Hb is abnormally seen diluted inRBCs - such as iron deficiency anaemia or thalassaemia

Increased such as spherocytosis

Helps with interpretation of MCH and diagnosing specific red cell disorders.

Q

What is RDW in FBC

A

Red cell distribution width

Calculates variation in the size of your RBcs

In some anaemias such as iron deficiency there is increase in variation of RBC size

16
Q

When might eosinophil WBC count be higher in FBC

A

Due to atopy or drug allergies.
Hodgkins lymphoma
Bone marrow disorder
Vasculitis

17
Q

When might neutrophil count be raised in FBC?

A

Dynamic so can vary day to day. Normal varies between ethnic groups

18
Q

When might lymphocyte be different in FBC?

A

Increased or decreased by viral infection

Increased in chronic lymphocytic leukemia

19
Q

When might monocyte be raised in FBC?

A

Some types of infection e.g TB

or bone marrow disorder e.g. myelodysplasia

20
Q

When might basophil be changed in FBC?

A

Increased with some infections, inflammatory disorders, and some bone marrow disorders eg chronic myeloid leukaemia.

21
Q

when might RBC be increased in FBC

A

When too many are made, and with fluid loss due to diahrrohea dehydration and burns

22
Q

The might MCV be increased in FBC?

A

Elevated = RBC larger than normal e.g. in anemia caused by folic acid deficiency.

Liver disease
Underactive htroid
Pregnany
Alcohol Excess

23
Q

When might platelets count be increased in FBC?

A 
Bleeding
Inflammation
Infection
Surgery
Bone marrow disorders
Absent or underactive spleens
24
Q

When might platelets count be decreased in FBC?

A 
Immune conditions such as SLE or ITP
Vitamin deficiences
Some drugs esp chemo
liver disease
alcoholicism
enlarged speleen 
Wiskott Aldrich
