Worked Solution & Example Answer:A person had symptoms including difficulty passing urine, aching in the lower abdomen, constant thirst and fainting - Edexcel - GCSE Biology - Question 6 - 2019 - Paper 1
Step 1
Give a reason why the doctor came to this conclusion.
Answer
The presence of excess glucose in the urine, which is indicative of higher blood glucose levels, suggests that the person may have diabetes. The abnormal result showing 200 mg per dl of glucose exceeds the acceptable range and may lead the doctor to suspect type 2 diabetes.
Step 2
Explain why the doctor also concluded that the person had a kidney infection.
Answer
The elevated level of leukocytes (40 white blood cells per dl) in the urine is significantly higher than the normal range (2 to 5). This suggests an inflammatory response typical of a kidney infection, as the body's immune response leads to an increase in white blood cells in the urine.
