Lab case 447 interpretation
Question 1:
• Hb = 76 (between 7 and 9.9) = moderate anaemia.
Normal MCH and MCV so we have normochromic anaemia.
• WBC = 1.5 (N = 0.9) = mild leukopenia with moderate neutropenia.
• Platelets = 31 (between 70 and 20) = moderate thrombocytopenia.
Lab case 447
21 year old girl presented with sudden left sided weakness. Her CT head showed intracerebral haemorrhage. Her full blood picture showed the following:
Lab case 446 interpretation
PH = 7.238, that is moderate acidaemia.
pCO2 = 49.1 mmHg. that is suggestive of respiratory acidosis
HCO3 = 20.2 mmol/L, that is suggestive of metabolic acidosis.
Lab case 446
The following blood gases results were given to a doctor to sign, explain the findings
PH = 7.238
pCO2 = 49.1 mmHg
pO2 = 47.7 mmHg
lab case 445 interpretation
Answers:
Ph = 7.51, that is mild alkalaemia.
HCO3 = 47.5 mmol/L. So, we have metabolic alkalosis.
Lab case 445
85 year-old-woman with fracture of right neck of femur. Her blood gases showed the following:
PH = 7.51
pCO2 = 59.5 mmHg
pO2 = 70 mmHg
HCO3 = 47.5 mmol/L
Lab case 444 interpretation
Answers:
Ph = 7.25, that is moderate acidaemia.
pCO2 = 58 mmHg, so we have respiratory acidosis.
