Flashcards in Lab Deck (16):
Dissolves cellular elements, preserves fungi & protozoa. Different species present under microscope in varied ways
Identification of + or - bacteria to determine initial antibiotic therapy. ID presence of bacteria in typically sterile media
Identification of blanching versus non-blanching skin issues. Using microscope slide.
Bacterial (wound) culture
Swab of wound to guide abx therapy to targeted organism and susceptibility to abx. Must swab prior to initiation of therapy
Swab from active lesion, unroof lesion and swap at deepest point. Allows different ion between types of viruses
Swab site of active lesion to determine which type of virus is causing the infection
Confirm or establish fungal or yeast infection. Takes 2-8 weeks. Good for infections that aren't resolving with standard therapy
Detection of warts using acetic acid (vinegar). Warts appear white.
Gold statndard in herpes dx. Deroof blister, fix and stain. Appear as multinucleate or giant cells under microscopy. Cant differentiate between subtypes
Ultrasound- accumulation of fluid give cobblestone appearance. CT if extensive infection
T2 weighted MRI- only indicated to rule out. See extent of damage to facial plane. If high suspicion schedule with surg.
CT scan. extraluminal and deep gas shows up black
MRI- not specific- evaluate extent of soft tissue involvement and debridement
MRI- prompt detection of spinal problems and bony involvement
unexplained swelling, potential infections or inflammatory process- diagnostic or therapeutic
