INTENDED USE
Hardy Diagnostics CVM Transport Media is provided in plastic centrifuge tubes and is used for the collection and transport of clinical specimens for the recovery of chlamydial, viral, and mycoplasmal agents including: Herpes Simplex Type I, Herpes Simplex Type II, Cytomegalovirus (CMV), Influenzae A, Influenzae B, Respiratory Syncytial Virus (RSV), Echovirus, Adenovirus, Chlamydia trachomatis, Chlamydia pneumoniae, Mycoplasma hominis, Mycoplasma pneumoniae and Ureaplasma urealyticum.
SUMMARY
CVM Transport consists of Modified Hank's Balanced Salt Solution supplemented with bovine serum albumin, sucrose, glutamic acid, and gelatin. A buffer is used to maintain a pH of 7.3 +/- 0.2. Phenol red is used as a pH indicator. Amphotericin B (4ug/ml), colistin (7.5ug/ml), and vancomycin (100ug/ml) are added to inhibit contaminants. The media contains cryoprotectorants to ensure viability of organisms during freezing and thawing. Some users prefer the presence of beads in the tube (Cat. no R396 and R396K) in order to assist in the lysing of tissue cells to release the pathogenic agent.
Some of the CVM kits (R96KF, R96KM, and R96KNP) are now supplied with nylon flocked swabs. Diagnostic sensitivity of test procedures can vary depending on the number of cells and free organisms released by the transport swab. Based on recent studies, samples collected with nylon flocked swabs yield more epithelial cells than those collected using rayon or dacron swabs, thus providing better clinical specimens for diagnosis. Flocked swabs are compatible with rapid antigen kits, DFA, culture, and PCR.(6,7)
STORAGE AND SHELF LIFE
Storage: Upon receipt store at 2-8 degrees C. away from direct light. Media should not be used if there are any signs of deterioration (shrinking, cracking, or discoloration), hemolysis, contamination, or if the expiration date has passed. Product is light and temperature sensitive; protect from light, excessive heat and freezing at temperatures above -70 degrees C.
The expiration date applies to the product in its intact packaging when stored as directed.

PRECAUTIONS
This product is for in vitro diagnostic use only and is to be used only by adequately trained and qualified laboratory personnel. Observe approved biohazard precautions and aseptic techniques. All laboratory specimens should be considered infectious and handled according to "standard precautions". The "Guideline for Isolation Precautions" is available from the Centers of Disease Control and Prevention at www.cdc.gov/ncidod/dhqp/gl_isolation.html.
For additional information regarding specific precautions for the prevention of the transmission of all infectious agents from laboratory instruments and materials, and for recommendations for the management of exposure to infectious disease, refer to CLSI document M29.
Sterilize all biohazard waste before disposal.
Refer to the keyword "Precautions", in the Hardy Diagnostics software program HUGO™, for more information regarding general precautions when using culture media.
Refer to the keyword "MSDS", in the Hardy Diagnostics software program HUGO™, for more information on handling potentially hazardous material.
PROCEDURE
Aseptically collect sample. Use swabs and shafts that are non-toxic to chlamydial, mycoplasmal, ureaplasmal, and viral agents, such as dacron or nylon flocked swabs on plastic shafts. Do not use cotton or calcium alginate swabs for collection of specimens.
After collection of specimen, remove cap from tube, insert swab. Submerge the tip of the swab into the media so the tip contacts the bottom of the tube. Break off the top third of the swab by bending the shaft against the rim of the tube. The shaft is scored to facilitate breaking. Re-cap the tube securely. Label the sample. Transport immediately to the lab at 2-30 degrees C. within 48 hours. Upon arrival to the lab, refrigerate at 2-8 degrees C. For long-term storage, freeze at -70 degrees C. Do not freeze at temperatures higher than -70 degrees C. For more information, consult listed references.(2-5)
More than one tube may be submitted if more than one type of culture is requested to ensure adequate specimen for culture set-ups.
All specimens should be shipped in compliance with all federal, state and hospital guidelines.
INTERPRETATION OF RESULTS
Consult listed references for isolation and identification procedures for specific organisms recovered from transport media.(2-5)
LIMITATIONS
Inoculate specimens as soon after collection as possible. This transport has been validated to maintain viability of organisms during transport at room temperature for 48 hours. If there is to be a delay in inoculating, store at 2-8 degrees C. For long-term storage of specimens for recovery of chlamydial, viral, and mycoplasmal agents, freeze at -70 degrees C. Freezing at higher than -70 degrees C. is not recommended.
Repeated freezing and thawing of frozen specimens may reduce the recovery of viable organisms.
Nylon flocked swabs, dacron or rayon tipped swabs are recommended. Calcium alginate or cotton swabs, as well as wooden stick swabs, should not be used.
Determinations for recovery of specific serotypes of C. trachomatis were not included in the study (see Performance Characteristics section).
Data represented in the Performance Characteristics section is for culture only. Performance has not been established for EIA testing. It is recommended that each laboratory establish performance characteristics of this product in conjunction with its chlamydial, viral, and mycoplasmal testing methods.
If culturing for cytomegalovirus and transport is at room temperature, the transport time should not be greater than 24 hours. If transported at 2-8 degrees C. the transport time should not be greater than 72 hours.
Refer to the keyword "Limitations", in the Hardy Diagnostics software program HUGO™, for more information regarding general limitations on culture media.
MATERIALS REQUIRED BUT NOT PROVIDED
Standard microbiological supplies and equipment such as loops, incinerators, incubators, centrifuge, pasteur pipets, culture media and cell culture media, etc., as well as serological and biochemical reagents, are not provided.
QUALITY CONTROL
The following organisms are routinely used for testing at Hardy Diagnostics.
After inoculation to the CVM Transport Media, the organisms listed below are held at 2-30 degrees C., for the indicated time, and then subcultured to appropriate culture media.
| Test Organisms | Time | Reaction |
| Mycoplasma pneumoniae ATCC® 15531 |
48hr | Viability maintained |
