Investigations
Full Blood Count
- shows red blood cell count , total haemoglobin , haematocrit , white blood cell count ,platelet count
Haemoglobin - normal range : 13.5-17.5 g/dl (male )
: 11.5-15.5 g/dl (female )
Has oxygen carrying capacity. Hence, if person has low haemoglobin count, might cause anemia in patients, post operatively.
Anaemia - condition where r.b.c or r.b.c carrying capacity drops below normal levels.
- symptoms : tiredness, lethargy, shortness of breath , palpitations
- signs : palor , smooth tongue ( abnormal ) , painful ulcers
White Blood Cell Count
- doesn’t have much significance in prevalence of unexpected abnormalities postoperatively. ( only 1 % )
- patient management also not altered.
- usually indicated by myeloproliferative disorders, high risk of leukopenia from drugs/disease
Platelet Count
- important function in blood clotting .*
- normal range : ( 150- 400K /microlitre )
- reduced level could cause problems during cataract surgery. ( invasive )
Coagulation Tests
- Related to platelet function
- Eg: Thrombin Time - thrombin added to plasma and time taken to form a clot is
- recorded. ( should be <>
- extended period of time could suggests drug use ( aspirin ) , haemophilia.
Fasting Blood Glucose
range : -
- done by asking patient to cease eating any food for about 8 hours, then blood glucose tested with glucometer.
- important to make sure patient is not diabetic.
