Feces Adenovirus, astrovirus, CMV, norovirus, rotavirus Fecal specimens (preferred) in a leak-proof container fecal swabs in VTM Genital Adenovirus, CMV, HSV, papillomavirus, varicella-zoster virus (VZV) Collect on swabs and transport in VTM Respiratory Adenovirus, coronavirus, hantavirus, CMV, HSV, influenza virus, parainfluenza virus, metapneumovirus, measles virus, rhinovirus, RSV, VZV Nasopharyngeal aspirates (NPA) are specimens of choice from children, NPA or nasopharyngeal swabs collected from adults bronchoalveolar lavage for the diagnosis of lower respiratory tract infections. Body Sites Potential Viruses Specimen Collection Eye Adenovirus, enterovirus, coxsackievirus A, cytomegalovirus (CMV), herpes simplex virus (HSV), varicella-zoster virus (VZV) Collect conjunctival swab on Dacron or rayon swab moistened with saline and place in VTM aqueous and vitreous fluid placed in a sterile container without VTM. Viral Transport Media (VTM) is used to transport the following specimens. Liquid specimens such as CSF, bronchoalveolar lavage fluid, or urine should not be diluted in viral transport media. Preserves viruses and chlamydiae for long-term frozen storage.Suppresses bacterial and fungal contamination by incorporating antibiotics in the medium.Offers flexibility in transport temperature ranges–room temperature or refrigerated.Sustains viability for culture and nucleic acid amplification test (NAAT) of viruses, chlamydiae, mycoplasmas and ureaplasmas in a single formulation by “preserving” and “stabilizing” them.Antibiotics are usually incorporated in viral transport media to suppress the growth of contaminating bacteria and fungi, so separate specimens from the same site must be collected if bacterial or fungal cultures are also requested. It maintains organism viability for 48 hours at room or refrigerated temperature.Ĭommercially prepared VTM is available in a plastic screw cap tube that contains buffered protein (serum, albumins, or gelatin) and antibiotics. Viral Transport Media (VTM) are suitable for collection, transport, maintenance, and long-term freeze storage of clinical specimens containing viruses, chlamydia, mycoplasma, or ureaplasma organisms.
