  1. Specimen collection Role of the Nurse

  2. Nurses often assume the responsibility of specimen collection • Specimens consist • Urine • Stool • Sputum • Wound drainage • Blood

  3. What about the client? • Comfort • Privacy • Questions • Clear, concise directions • NPO

  4. The Nurse • Check physician orders • Keep it Simple directions to client • Standard precautions • Label specimen • Timely • C&S to lab ASAP or refrigerated • Documentation

  5. Urine Specimen • Random • Clean • Female ? Menses (make note) • Tested for: • Specific gravity • pH • Albumin • Glucose • Microscopic exam

  6. Urine for C&S • Culture = ? Bacteria growing • Sensitivity = which antibiotics are effective • Readings after 24; 48; 72 hrs. Midstream Urine Sterile Catheter Specimen (never from bag)

  7. Why a urine specimen for C&S • ? Urinary Tract Infection (UTI) • Frequency • Urgency • Dysuria • Hematuria • Flank pain • Fever • Cloudy, malodorous urine

  8. Obtaining specimen • Wash hands • Clean meatus, female front to back • Start stream, then stop, collect specimen • Aseptic technique • Bedpan/mexican hat • To lab 15-20min post collection

  9. Children • Pediatric bags ( u Bag) • Never squeeze diaper

  10. Characteristics of Urine • Color • Clarity • Odor

  11. Specimen Collection • Random Specimens • Clean-not sterile • Ordered for • Urinalysis testing • Measurement of specific gravity • pH • Glucose levels

  12. Urine specimen collection • Midstream Specimen • Clean voided • C&S • 30-60 mls urine • Sterile Specimen • Indwelling catheter • Drainage bag

  13. Urine collection • Timed urine specimens • 2-72 hr intervals (24hr most common) • Begin after urinating • Note start time on container & requisition • Collect all urine in timed period Post Reminder Signs

  14. Indwelling Catheter • Strict aseptic technique • Only from Bag if Brand new • Sampling Port? • Clamp 30 min. prior • Wash hands – Glove • Cleanse port with alcohol swab • Sterile needle • To lab 30 min (may refridge 2hrs)

  15. Common Urine Lab Tests • Routine Urinalysis • Examine within 2hrs • 1st voided specimen in AM • Reagent strip • Specific Gravity • Concentration • 1.010-1.025 • Urine glucose • Diabetics • Reagent strips • Double void

  16. Measuring chemical properties of urine=Urinalysis • Glucose • Ketones • Protein • Blood- hematuria • pH • Specific gravity • Microscopic examination

  17. Stool Specimen Analysis of fecal material can detect pathological conditions ie: tumors, hemorrhage, infection • Tests • OB • Pus • Ova & Parasites

  29. Stool Specimen Analysis of fecal material can detect pathological conditions ie: tumors, hemorrhage, infection Tests OB Pus Ova & Parasites

  30. Fecal specimens • ? Chemical preservatives • Medical aseptic technique • To lab on time • Labelling • Documentation Guaiac Test Colorectal cancer screening test FOBT Hemoccult slide test

  31. Fecal Characteristics • Color • melena • Odor • Consistency • Frequency • Amount • Shape • Constituents

  32. Guaiac Test • Single positive test result does not confirm bleeding or colorectal cancer. • Repeat test 3X • Meat free, high residue diet
