Labcorp 1 test

Single-analyte tests

  • GC ( Neisseria gonorrhoeae ) Culture Only 008128

    Swab · Fasting not stated · Turnaround 4 - 5 days

    Method and collection
    Method
    Culture on selective media; MALDI-TOF and/or biochemicals for identification
    Collection
    Do not collect urethral specimens until at least one hour after urinating. Collection directly from male urethral discharge is desirable. Collect anorectal specimens from the crypts just inside the anal ring; anoscopy useful. Prostatic fluid yields fewer positives than does urethral culture. Endocervix: Swab endocervical canal. Avoid contaminating swab with vaginal secretions. Cultures from the urethra or vagina are indicated from females when endocervical culture is not possible. Urethra: Strip the urethra toward the orifice to express exudate. Use a sterile swab to obtain the specimen. Vagina: Use a speculum, moistened only with warm water, not lubricant. Obtain a specimen from the posterior vaginal vault or from the vaginal orifice if the hymen is intact.

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
