Clinical Significance: To diagnose three sexually transmitted infections associated with vaginitis.

Test code: 3946

CPT code(s): 87168

Clinical significance: Arthropods/insects may be vectors of disease and may cause infestations of skin, hair, and mucous membranes. Diagnosis of a disease or infestation may be achieved by recovery and identification of the intact arthropod/insect.

Methodology: Microscopic and Macroscopic Examination

Alternative name(s): Tick Identification, Parasite Identification, External, Arthropod Identification

Test code: 3950

CPT code(s): 87169

Clinical significance: Some parasitic diseases can be diagnosed by recovering the intact parasite in adult, immature or larval form. The symptoms of the diseases caused by each parasite varies, dependent upon the type of parasite.

Methodology: Microscopic and Macroscopic Examination • Conventional Identification Techniques

Test code: 34118

CPT code: 87077

Clinical Significance: Aerobic Bacteria Identification is required for selecting optimal therapy.

Methodology: Matrix Assisted Laser Desorption/Ionization-Time of Flight
