Q: How does Amniotest™ work?
A: Amniotest is a nitrazine tipped swab that functions as a pH indicator. The presence of Amniotic fluid in a patients upper vaginal / cervical area may be determined by measuring the pH of the area using a swab to collect a sample and nitrazine indicator to guage pH. Amniotest is simply the combination of a swab and nitrazine indicator into a single product.
Q: What are the benefits of the Amniotest Swab?
A: The benefits are threefold. First, Amniotest comes in sterile, individually sealed, easy to open sleeves. Secondly, Amniotest conveniently combines nitrazine dye and the sampling swab together, thus eliminating the extra, cumbersome steps of traditional testing . Finally, Amniotest requires minimal Q.C. measures that will no doubt satisfy your accreditation inspectors, P.O.C. protocol directives, and department heads.
Q: What can cause a false negative reading?
A: Initially, it is important to remember that the Amniotest swab is not a protein-specific assay, but a pH indicator. Once the swab has passed the quality control regimen ( i.e. the swab performs well with the buffer solutions), a false negative simply means that the pH of your sample has been affected by other factors such as urine, blood.
Q: What about false positives?
A: False positives can be caused by a variety of factors. The most common cause of false positives are vaginal / urinary tract infections, some topical creams, and antibiotics.
Q: What is the recommended Q.C. regimen?
A: For new users, it is recommended that Quality Control be performed on a per box basis with six swabs and all six buffer solutions in order for the user to become familiar with the product and interpreting the results. After which, the standard Q.C. regimen is performed on a per lot basis with the upper and lower pH ranges (5.0 and 7.5)
