Depending on the symptomatology, examinations concerning the bladder, vulva, and vagina and, to clarify menopausal symptoms, hormone status are useful and necessary. Laboratory parameters of the 1st order – obligatory laboratory examinations
Bladder/urethra
- Urinalysis by test strip:
- A rapid test for nitrite detects nitrite-forming bacteria in the urine, if necessary. [Nitrate detection in urinary tract infection (UTI): 95% with a positive nitrate test have positive cultures, although 45% with a negative test]Leukocyturia may also be detectable. [according to German S3 guidelines, a HWI is considered likely if nitrite or leukocyte esterase test positive].
- Urine pH values > 7.0 in the pH daily profile = indication of a urinary tract infection with urease-forming bacteria (risk of infection stone formation).
- Urine sediment
- Urine culture (pathogen detection and resistogram) from midstream urine possibly catheter urine in acute chronic recurrent cystitis (recurrent cystitis.
Note: further details on the clarification of urinary tract infection or chronic recurrent infections see chapter cystitis (cystitis).
Vulva / vagina
- Amine test (Whiff test) – by sprinkling the vaginal secretion (vaginal secretion) with a 10% potassium hydroxide solution typical fishy smell (= amine colpitis).
- Measurement of the pH of the vaginal secretion [alkaline?]
- Phase contrast microscopy of vaginal secretion – live, unstained cells appear extremely low contrast in a normal brightfield microscope, these are clearly visualized by the phase contrast technique
Hormone parameters
- FSH (follicle-stimulating hormone).
- LH (luteinizing hormone)
- 17-beta estradiol
Laboratory parameters 2nd order – depending on the results of the history, physical examination, etc. – for differential diagnostic clarification.
Bladder/Urethra
- Small blood count
- Inflammatory parameters – CRP (C-reactive protein) or PCT (procalcitonin).
- Fasting glucose (fasting plasma glucose).
- If necessary, exclusion of venereal disease – in cystitis with adnexitis, colpitis.
- Urine cytology
- BK (polyoma) virus DNA detection – in immunocompromised individuals, BK virus can lead to hemorrhagic cystitis.
Vulva/Vagina
- Bacteriological/mycological/virological culture – cultivation of bacteria/fungi from the vulva and/or from vaginal secretions in recurrent colpitids.
- Bacteria: Chlamydia trachomatis (lymphogranuloma venereum, cervicitis, adnexitis), Neisseria gonorrhoeae (gonorrhea), Treponema pallidum (syphilis), Ureaplasma urealyticum (cervicitis, adnexitis, urethritis), and others
- Fungi: Candida albicans and other Candida species: (urethritis, vaginal mycosis, vaginal candidiasis).
- Viruses: herpes viruses (cultivation from vesicle contents) method of choice.
.
- Virus detection
- Molecular genetic diagnostics (DNA or PCR): HIV (AIDS), herpes simplex virus type 1/2 (genital herpes), human papilloma virus (HPV; condylomata acuminata).
- Other detection: herpes viruses:
- From vesicle smear applied to a microscope slide. Determination of the virus type by fluorescence test using type-specific immune sera if necessary direct antigen test (fluorescence test).
- Histologically after biopsy
- Colposcopic: dabbing with 3% acetic acid (affected skin areas turn white).
- Cytological smear
- Parasite detection (microscopic): crabs (pediculosis pubis), mites, oxyuras, scabies, Trichomonas vaginalis (trichomoniasis).
- Antibodies against Chlamydia trachomatis, HSV type 1 u. 2, HIV, Treponema pallidum (TPHA, VDRL etc.) – due toexclusion of sexually transmitted infections.
- Biopsy for histological examination
- Cytology
Hormone parameters
- TSH
- Prolactin
- Estrone
If necessary, further (as far as not yet determined).
- Small blood count
- Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate).
- Urine status (rapid test for: pH, leukocytes, nitrite, protein, glucose, ketone, urobilinogen, bilirubin, blood), sediment, if necessary urine culture (pathogen detection and resistogram).
- Fasting glucose, if necessary oral glucose tolerance test (oGTT).
- Liver parameters – alanine aminotransferase (ALT, GPT), aspartate aminotransferase (AST, GOT), glutamate dehydrogenase (GLDH) and gamma-glutamyl transferase (gamma-GT, GGT), alkaline phosphatase, bilirubin.
- Renal parameters – urea, creatinine, cystatin C or creatinine clearance, if necessary.
- Atherosclerosis parameters:
- Total cholesterol, LDL cholesterol, HDL cholesterol.
- Triglycerides
- Homocysteine
- Vitamins D3, B6, B12, folic acid, trace elements selenium and zinc.
- Fecal occult blood test
