Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid translating as 'лактозурия' without context; it is an opaque medical term. Do not confuse with 'лактозная недостаточность' (lactose intolerance), which is a related but broader condition.

Common Mistakes

  • Misspelling as 'lactosuria' (missing 'o').
  • Using it as a verb (e.g., 'The patient lactosurias').
  • Confusing it with glycosuria (glucose in urine).

No. It is an asymptomatic biochemical finding detected only by urinalysis.

The presence of lactose in urine is not directly harmful. The concern lies with the underlying condition causing it, such as intestinal damage or enzyme deficiency.
