Question | Answer |
Prolactin level: to dx: | pituitary adenoma, amenorrhea, galactorrhea, hypothalamic pituitary disorders |
PCOS: lab values | LH, testosterone, prolactin high; progesterone, estrogen low. Also check FSH (to r/o premature ovarian failure), DHEA, TSH, lipids, A1c |
Wet prep swab | cotton swab; rotate over vaginal wall/inflammation; avoid cervical mucus/blood; in 1 mL saline; to lab within 20 min |
Cervical testing | no bathe 24 hrs; unlubricated speculum; remove cerv mucus w/cotton swab; sterile swab into canal 15-30 sec; plate or media |
Gono cx plates | TM, choc, or Jembec (CO2 reservoir); swab in Z pattern & cross streak; 36C (don’t refrigerate) |
Gram stain for Gyn specimen | urethra: Ca alginate 1-2 cm x 3-5 sec (females more shallow); cervical: cotton swab, usu not done (gold std for clue cells) |
Oropharyngeal NG cx | swab posterior pharynx & tonsillar crypts; include areas of inflammation or exudate |
Urethral NG cx | Collect ≥1 hr post urination; ideal: prior to first morning micturition; swab anterior urethra |
HSV cx | vesicle: unroof lesion (18 ga needle), abrade w/cotton swab; crusted: remove crust w/moist gauze, scrape w/cotton swab; transport medium, refrigerate if delay |
HSV serology | less sensitive; helpful if IgM or high IgG |
4-fold rise in HSV titer = | acute initial HSV infxn |
Darkfield for syphilis | pos = dx; not definitive if neg |
Syphilis: nontreponemal tests | RPR more sensitive than VDRL; VDRL pos 2 wks after inoculation, pos thru secondary and often in tertiary |
All syphilis tests 100% sensitive in stage: | secondary |
Syphilis: treponemal test | FTA; more specific, pos 4-6 wks post inoculation; FTA-Abs (sandwich): more sensitive = definitive test; MHA-TP |
NG tests | gram stain, cx (specify suspicion), NAAT (DNA by PCR) |
Chancroid tests | cx (specify suspicion), DNA PCR, no serology |
Chlamydia tests | NAAT (DNA by PCR); cx & sero outdated |
LGV test | complement fixation |
GN bipolar rods encapsulated in mononuclear lymphs = | Granuloma inguinale (donovan bodies) |
Women <21 yo w/ASCUS or LSIL | repeat pap in 12 mos |
Women <21 yo w/ HSIL | colposcopy +/- cytology |
Adult women w/ASCUS (Atypical squamous cells of undetermined significance) | repeat cyto (6 & 12 mos), HPV DNA, and colposcopy |
Adult women w/ASCUS-H | colposcopy; if neg: cyto (6 & 12 mos), HPV DNA q 12 mos |
Adult women w/ LSIL (low-grade cervical intraepithelial neoplasia) | Colpo, then endomet bx; if no CIN: cyto (6&12) & HPV DNA (12 mos) |
Adult women w/ HSIL (high grade cervical intraepithelial neoplasia) | immediate excision OR colpo, then observe or dx excision |
Adult women w/ AGC (atypical glandular cells) | endomet/endocerv bx, then colpo |
indications for endometrial ca testing | AUB >35-40 yo; AGC on Pap (also needs Colposcopy); Benign Endometrial Cells on pap if woman post menopausal |
endomet bx advantages | in office; minimal dilation; anesthesia not req; prophylactic Abx not req; low cost |
amenorrhea labs | HCG, FSH, estrogen, prolactin, testost; progesterone challenge to detn if suff estrogen |
FSH of ___ is diagnostic of menopause | >30 mIU/mL |
Dysfunctional uterine bleeding labs | CBC, Fe, coags, HCG, TFT, LFT, progesterone, prolactin, FSH |
Dysfunctional uterine bleeding studies | US, pap, endometrial bx |
endometrial ca dx studies | pap, endocervical curettage, endomet bx (90-95% accuracy); TVUS? |
string of pearls within ovaries on US = | PCOS |
ovarian ca dx | 5% BRCA1; CA-125; P53 tumor suppressor gene mutation; TVUS |
Next test when colpo results unsat or endocervical curettage shows severe dz: | conization |
Infertility testing | Semen analysis. Confirm ovulation. Luteal phase endometrial bx. FSH, prolactin, TSH. Serum progesterone at secretory phase midpoint (day 21). Hysterosalpingogram. |
PID testing | DNA probe for GC/CT; TVUS; poss dx culdocentesis |
Chlamydia labs | complement fixation or immunofluorescence; ELISA; or DNA probe |
Tests for trichomonas | OSOM rapid test. Affirm VP III (nucleic acid probe test). Both 83% sens, 97% spec. |
Male vs female contributions to infertility | Male in 40% of cases. Female: anovulatory cycles, congenital / acquired fallopian/cervical/uterine problems. 60% of couples PG within 3 years |
Cervical cancer dx studies | Pap. Colposcopy & bx for staging. Conization if colposcopy nondiagnostic. MRI, CT, pelvic lymphangiography to demonstrate pelvic involvement. Advanced dz: cystoscopy, sigmoidoscopy. CXR to r/o mets |
LH:FSH ratio of 3:1 suggests: | PCOS |
