ROM Plus provides reliable sensitivity delivered conveniently and cost effectively.

ROM Plus® is unique in that it detects both Alpha-fetoprotein (AFP) and Insulin-like growth factor-binding protein 1 (IGFBP-1) using a monoclonal/polyclonal antibody approach–improving its sensitivity.

Timely and accurate diagnosis of PROM allows for gestational age-specific interventions designed to minimize the potential risk of complications to both mother and baby.

Dual Protein Markers: Placental Protein-12 & Alpha-fetal Protein

  • IGFBP-1 is detected early in first trimester and “plateaus” throughout the duration of the pregnancy
  • AFP is detected at the end of the 2nd trimester/beginning of the 3rd trimester (< 37 weeks) where full confidence is required in the accurate diagnosis
  • AmniSure and Actim PROM tests only employ one protein marker

Monoclonal Antibodies

Recognizes only one epitope on an antigen
Polyclonal Antibody-01

Polyclonal Antibodies

Recognizes multiple epitopes on any one antigen

Polyclonal & Monoclonal Antibody Approach:

  • Reduces the chance of false negatives
  • Provides a better “screening” method to detect the presence of protein markers
  • Improves the opportunity for denatured protein detection
  • AmniSure and Actim PROM tests only employ a monoclonal antibody approach

Ease of Use:

Additionally, ROM Plus ES has:

  • Spill resistant vial to avoid accidental spilling of buffer solution and/or sample

I’m a believer!

“The transition from AmniSure to ROM Plus was incredibly easy. I was anticipating push back from the staff but I had absolutely none. The staff felt that ROM Plus was a reliable test and even easier to run than their previous POC test. The ROM Plus representatives were organized, friendly and made the transition that much easier. Very rarely can you make a transition to a product that is easier to use and clinically reliable, all while saving the hospital thousands of dollars a year. I’m a believer!”

Sensitivity is the percentage probability that a positive test will occur in a patient who is really experiencing rupture of membranes, or the proportion of actual positives which are correctly identified as such. In a multi-site hospital study involving 285 patients, ROM Plus ES resulted in an overall sensitivity of 99.5% (see IFU for details).

ROM Plus ES test kits have been tested up to 10% blood concentration. In other words, it will function properly with trace amounts of blood in the sample, however, significant amounts of bloody discharge may cause the test to malfunction. ROM Plus ES is not recommended for use in these situations and it should be determined what is causing the bleeding.

If only a control line (C) is visible, the test result is negative (no PP12 and/or AFP were detected). If both the control line (C) and test line (AF) are visible, the test result is positive (PP12 and/or AFP was detected). If no lines are visible, or just the test line (AF) is visible, the test result is invalid and should be repeated. Darkness of the stripes may vary. The test is valid even if the stripes are faint. Do not interpret test results based on darkness of the stripes.
ROM Plus ES should be stored in a dry place at 4° to 24°C (40° to 75°F). DO NOT FREEZE. When stored in the foil pouch at the recommended temperature, the test is stable until the expiration date. Use ROM Plus ES within six (6) hours after opening foil pouch. Use ROM Plus ES within six (6) hours of collecting the vaginal swab sample and placing it into the buffer vial.

The lyophilized positive and negative controls can be stored in a dry place at room temperature until the expiration date. No refrigeration is required.

Tylenol, aspirin, Lever Soap, Noxema cream, Pert Shampoo, human semen, urine and blood were tested as possible interference’s and were shown to be negative.

ROM Plus ES does not have any gestational age limits.
