Extract ALL laboratory and microscopy results from this medical document. Return a JSON array of lab orders, or null.

Each lab order groups results from the same test panel or section of the document:
- type: "lab_order"
- value: panel/section name (e.g. "Urinalysis", "Blood Parasite Dark-field Microscopy", "CBC")
- summary: same as value
- timestamp: "YYYY-MM-DD" if collection date mentioned
- results: array of individual test results, each with:
  - type: test name (e.g. "Urine Protein", "Epithelial Cells", "Blood Parasites")
  - value: result as string (numeric like "14.2", or qualitative like "POSITIVE", "NEGATIVE", "Candida albicans 4+")
  - summary: "test name: result [unit]", e.g. "Hemoglobin: 14.2 g/dL" or "Urine Protein: NEGATIVE"
  - search_key: test name lowercase
  - data: {"test_name": "...", "result": "...", "unit": "..."}
  - summary_translated and data_translated: same translation rules as the parent (translate into the target language specified in the preamble)

CRITICAL: Extract EVERY individual test result, including:
- Numeric results (e.g. Specific Gravity: 1.015)
- Qualitative results (POSITIVE, NEGATIVE, HAZY, YELLOW, etc.)
- Microscopy findings from tables or structured results (Epithelial Cells, Yeast Cells, Bacteria, Casts, Crystals, etc.)
- Parasite/organism identification results (Blood Parasites: Positive, Isolate: Borrelia, etc.)
Do NOT skip NEGATIVE results — they are clinically important.
Do NOT extract narrative descriptions or free-text observations — only structured test:result pairs.
Do NOT extract diagnostic summaries or interpretations (e.g. "Boreliosis", "Anaemia" — those are diagnoses).

Every entry MUST come from text explicitly present in the document. Do NOT infer or assume.
Return null if nothing relevant is explicitly described.
