Investigations

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.
