The diagnostic procedure for detecting head‑lice infestation is called a lice inspection. It involves visual examination of the scalp and hair for live lice or nits.
What is the examination for lice called? - in detail
The clinical assessment for a lice infestation is termed a «pediculosis examination». This evaluation determines the presence, species, and severity of infestation on the scalp or body.
Indications for performing the assessment include reported itching, visible nits, recent exposure to an infested individual, or routine screening in schools and childcare facilities.
The examination proceeds as follows:
- Visual inspection of the scalp and hair shafts under adequate lighting.
- Use of a fine‑toothed lice comb to separate hair strands and capture adult lice or nits.
- Systematic examination of the neck, ears, and shoulders for additional specimens.
- Documentation of findings, noting live insects, viable nits (attached within 1 cm of the scalp), and any secondary skin changes.
Essential instruments comprise:
- A high‑magnification headlamp or lamp with adjustable focus.
- A stainless‑steel or plastic lice comb with teeth spaced 0.2–0.5 mm apart.
- Disposable gloves to prevent cross‑contamination.
- A magnifying lens or handheld microscope for detailed inspection of collected specimens.
Interpretation criteria:
- Presence of live lice confirms active infestation; treatment should commence promptly.
- Detection of only viable nits without live insects suggests recent infestation; preventive measures and close monitoring are warranted.
- Absence of lice and nits indicates no current infestation; education on avoidance strategies may be provided.
Follow‑up involves re‑examination after 7–10 days to verify treatment efficacy and to detect any newly hatched lice that may have escaped initial removal.
