MERCY LAB CODE

EYEC

Order:

Indicate which eye when ordering. See beginning of section for ordering help and codes.

Specimen: 

• Conjunctivitis: 
  Touch the involved area with a sterile swab moistened with sterile saline. Ideally, inoculate directly to the appropriate media (Contact Microbiology).  However, the specimen may be transported on a routine culturette to the lab.
• Corneal scrapings: 
  The cornea may be anesthetized with 0.5% proparacaine hydrochloride, but better results are obtained if the scrapings are collected without the use of a topical anesthetic.  A topical anesthetic may have an antimicrobial effect.  Scrape the base and margin of the ulcer.  Inoculate these scrapings directly to the appropriate media.

Comment:

1. Deliver to Lab immediately. The organisms involved in eye infections are often fastidious in nature. 
2. Susceptibility testing will be performed on significant isolates.
3. This order is for INTERNAL eye specimens only. If an external eye culture is needed, order as a wound culture.

RL Client Comments:

1. Write EYE CULTURE on the order form. Indicate which eye was cultured.
2. Send the specimen room temperature to Mercy lab.

Performed:

Preliminary reports:  Days 1 & 2
Final report:  3 days
