IS IT THIS? - reference only, to read alongside your own examination
  TESTS (4)
    - More than 25 mg/dL glucose in a random fresh urine sample is pathological; below that is
      normal
    - In a patient with glycosuria, confirm or exclude diabetes with a fasting or random plasma
      glucose and HbA1c
    - Fanconi syndrome shows hypophosphataemia and metabolic acidosis alongside phosphaturia,
      aminoaciduria and glycosuria
    - Most semiquantitative dipsticks only read glucose between 50 and 250 mg/dL, so the strip is a
      poor quantitative measure
  IF NOT THIS - what else fits (7)
    - Only two mechanisms: plasma glucose above the renal threshold, or a proximal tubule that
      cannot reabsorb
    - Tubular causes are pregnancy, Fanconi syndrome, acute tubular necrosis, and familial renal
      glucosuria from an SGLT2 mutation
    - Alimentary glycosuria follows an excessive carbohydrate load in an otherwise normal person
    - The renal threshold rises with age, renal disease, heart failure and chronic hyperglycaemia -
      so urine glucose testing is of little value in long-standing diabetes
    - The threshold falls in hyperthyroidism, pregnancy, fever and exercise
    - SGLT2 inhibitors induce glycosuria deliberately, and raise the risk of genital and urinary
      tract infection and of dehydration
    - Post-load glycosuria is a poor predictor of gestational diabetes, pre-eclampsia and newborn
      size

1. NO DRUG THERAPY IN PRIMARY CARE (ASSESSMENT & ADVICE)  [1st line]
   Adult    Glucose in the urine is a common finding prompting diabetes screening in Egypt's high-
            prevalence population; management is directed at the underlying diagnosis, usually
            diabetes. - Assessment and advice
   Peds     Children follow the same pathway: assessment, explanation and follow-up. No primary-care
            medicine is implied.
   Source   No dose - no medicine is given for this in primary care
   Why      Glucose in the urine is a common finding prompting diabetes screening in Egypt's high-
            prevalence population; management is directed at the underlying diagnosis, usually
            diabetes.
   Caution  Glycosuria with classic symptoms (thirst, weight loss, frequent urination) or a very
            high blood glucose reading suggests new diabetes needing urgent assessment for
            ketoacidosis.
            No medicine is prescribed for this in primary care. The value of the consultation is
            recognition, explanation and follow-up, and referral if the red flags above appear.
            Non-diabetic or euglycemic glycosuria due to Fanconi syndrome is a red flag (tubular
            dysfunction causing phosphaturia, aminoaciduria, and metabolic acidosis).
            RED FLAG - Urine glucose testing has a diagnostic limitation: a detection threshold of
            50-250 mg/dL, and an altered renal threshold in aging or renal disease masking
            hyperglycemia.
