Tests and diagnosis

By Mayo Clinic staff

You or your doctor can usually confirm a pubic lice infestation through a visual examination of your pubic area. The presence of moving lice confirms infestation.

Lice eggs (nits) also may indicate an infestation. However, nits can cling to hairs and be present, although no longer alive, even after successful treatment.
