Bacterial Vaginosis/Vaginitis Panel (BD Affirm™) |
VAG MOLEC | 4604810 | ||||||||||||||||
CPT code: 87510, 87660, 87480RML is pleased to announce that we are now offering a vaginosis panel by molecular analysis. We will be utilizing the Becton Dickinson Affirm™ test, which is a qualitative molecular test to detect the presence of Candida species, Gardnerella vaginalis, and Trichomonas vaginalis. The detection threshold for Candida species and Gardnerella vaginalis distinguish between normal flora and clinically significant levels of organisms. Microscopy detection for Trichomonas vaginalis can be negative in up to 50% of women with culture-confirmed trichomoniasis. The BD Affirm™ provides more accurate detection of trichomoniasis. There is a broad differential for the diagnosis of vaginitis, and successful treatment depends on an accurate diagnosis. Published performance data for the BD Affirm™ test is as follows:
*Compared to culture (symptomatic patients) Specimen Requirements:BD Affirm™ VPIII Ambient Temperature Collection SystemThis collection system consists of a sample collection tube, sterile swab, and ATTS (ambient temperature transport solution). The ATTS must be used with the sample. The sample is stable for 72 hours at ambient or refrigerated temperatures. Testing Schedule:This assay is set up Monday through Friday and reports 1-3 days following set up. |

Molecular Clostridium difficile |
C DIFF DNA | 6001200 |
CPT code: 87493This is a molecular test that amplifies the pathogenic locus of the toxin producing section of the DNA and amplifies it by LAMP (loop mediated amplification technology) so it can be detected by a turbidity. The method used is called iLLUMIGENE by Meridian Bioscience. Advantages over current EIA testingSensitivity and specificity are 95.2% and 95.3% as compared to the gold standard of toxigenic culture. The toxin EIA test has variable sensitivity depending on the study, but ranges from 35-80%. Requires only one specimen; some literature states that with EIA testing up to 3 stools needed to rule out. FDA approved for children and infants under the age of 2. The EIA test is not. Specimen Requirements:Unpreserved Stool sample (raw stool) orStool samples preserved in Cary-Blair Based Media (includes ETM, PARAPAK C&S, Cary-Blair) Specimens should be transported (if possible) at 2-8C, and stored at 2-8C before testing. Specimens should be tested as soon as possible, but may be held up to 24 hours at room temp (21-27C) or 5 days refrigerated. Specimens that can not be tested within these times should be frozen immediately and stored at -20C until tested. Specimens may be frozen and thawed once. Testing Schedule:As this test is a highly complex molecular test, it will be run twice daily effective June 6, 2011. |

Fecal Lactoferrin |
FEC LACTOF | 6002550 |
CPT code: 83630A qualitative assay that is 90% specific for identifying inflammation in patients with active Inflammatory Bowel Disease (IBD) that is a noninfectious inflammatory diarrhea e.g. IBD. It is highly specific to rule out Irritable Bowel Syndrome (IBS), useful in differentiating IBS from IBD. <10% of celiac patients will be positive for lactoferrin. Lactoferrin will be positive where you have a neutrophilic inflammatory process, i.e. bacterial derived inflammatory diarrhea (Salmonella, Shigella, Campy, C. difficile.). Fecal Lactoferrin is a better test than non-standardized microscopic examination for WBC's (Stool for Polys). The use of fecal lactoferrin to screen for inflammatory diarrhea selects specimens for which stool culture is fivefold more likely to yield an invasive bacterial pathogen. Specimen Requirements:Raw stool no preservatives. Testing Schedule:This assay is set up Monday through Friday and reports 1-3 days following set up. |

Trichomonas Antigen |
TRICH AG | 2915460 |
CPT code: 87808This immunochromatographic test for Trichomonas antigen is the most appropriate test to identify Trichomonas organism. This test will detect presence of viable or non viable organisms. Which is a very effective method over the microscopic examination, since extended times between collection and examination, often exceeded 24 hours, makes visual identification of non-motile organism difficult and often unsuccessful. Specimen Requirements:Saline wet prep Testing Schedule:Ideally swabs should be processed as soon as possible after specimen collection. |

Vaginosis Profile from Swab with Trichomonas Antigen |
V PROF SWB | 2915445 |
CPT code: 87205, 87808, 82120This vaginal profile provides an interpretation of they types of vaginal pathology seen in yeast infections, Trichomonas vaginalis, bacterial vaginosis and even mixed flora infections. The Trichomonas antigen along with gram stain and evaluation for yeast, clue cells, white blood cells and all bacterial types present. Whiff test (amine test) is reported as positive or negative. Specimen Requirements:BBL Red top culturette in Amies media (double swab) Testing Schedule:Ideally swabs should be processed as soon as possible after specimen collection. |

Yeast Culture |
C YEAST | 6002525 |
CPT code: 87106This test was developed as an alternative to the traditional fungal culture (C FUNGUS) which has turn around time approaching 4 weeks. Specimens are plated on chromogenic agar for ease of early identification and final reports are issued within 8 days. Susceptibilities will not be routine performed but would be available upon request. Specimen Requirements:BBL Swabs in bacterial transport media Testing Schedule:This assay is set up Sunday through Saturday and reports within 8 days following set up. |
