The invention describes a process for determining a biological state through the discovery and analysis of hidden or non-obvious, discriminatory biological data patterns. The biological data can be from health data, clinical data, or from a biological sample, (e.g., a biological sample from a human, e.g., serum, blood, saliva, plasma, nipple aspirants, synovial fluids, cerebrospinal fluids, sweat, urine, fecal matter, tears, bronchial lavage, swabbings, needle aspirantas, semen, vaginal fluids, pre-ejaculate.), etc. which is analyzed to determine the biological state of the donor. The biological state can be a pathologic diagnosis, toxicity state, efficacy of a drug, prognosis of a disease, etc. Specifically, the invention concerns processes that discover hidden discriminatory biological data patterns (e.g., patterns of protein expression in a serum sample that classify the biological state of an organ) that describe biological states.

A wetness indicator material may be used on a substrate to form a wetness sensor. The sensor may show either the presence or absence of an aqueous-based fluid or water-containing medium, such as vaginal fluid or urine in a personal hygiene article. The wetness sensor may be incorporated into the article. The wetness indicator material includes a standard colorant that does not change color when wetted. The standard colorant increases the range of hues exhibited by the wetness indicator material.

The invention concerns the identification of proteomes of biological fluids and their use in determining the state of maternal / fetal conditions, including maternal conditions of fetal origin, chromosomal aneuploidies, and fetal diseases associated with fetal growth and maturation. In particular, the invention concerns a comprehensive proteomic analysis of human amniotic fluid (AF) and cervical vaginal fluid (CVF), and the correlation of characteristic changes in the normal proteome with various pathologic maternal / fetal conditions, such as intra-amniotic infection, pre-term labor, and / or chromosomal defects. The invention further concerns the identification of biomarkers and groups of biomarkers that can be used for non-invasive diagnosis of various pregnancy-related disorders, and diagnostic assays using such biomarkers.

The premature rupture of amniotic fluid (PROM) may be discovered through a number of inventive means. Methods of evaluating whether PROM is present include; a) through the testing of the pH of vaginal fluids using an irreversible pH test; b) through the detection of analytes (e.g. enzymes) specific to amniotic fluid in the vaginal fluids; c) though the detection of hydrogen peroxide (H2O2) in the vaginal fluid; and d) through the detection of cholesterol in vaginal fluid. While individually indicative of PROM, it is desirable to combine at least two of these techniques to yield a powerful tool of even greater reliability. Test devices and feminine hygiene pads into which the test methods may be incorporated are also included herein.

An assay device for detecting amines within a test sample (e.g., vaginal fluid) is provided. The assay device comprises a detection zone within which a chemichromic dye is contained.

A wetness sensor for an absorbent article that is formed from an ink is provided. The ink includes a proton-accepting chromogen and a proton-donating agent (or color developer). Prior to use, the ink is generally dry and in a protonated form so that it has a visible color. However, upon contact with bodily fluids (e.g., urine, fecal matter, mucus, menses, vaginal fluid, etc.), water in the fluid can lead to deprotonation of the chromogen, thereby resulting in a shift of the absorption maxima of the chromogen towards either the red (“bathochromic shift”) or blue end of the spectrum (“hypsochromic shift”). To increase the rate of the color change during use, the present inventors have discovered that a specific type of proton-donating agent may be employed. More particularly, the proton-donating agent is an aliphatic carboxylic acid that is highly soluble in the bodily fluid (e.g., urine), and therefore results in a color change that is very rapid and may be detected within a relatively short period of time. The extent of the color change is also generally sufficient to provide a “real-time” indication of wetness on the absorbent article.

A method for diagnosing, or differentially diagnosing, an increased risk of pre-term birth (PTB) involves detecting or measuring increased expression of a biomarker Soluble E-cadherin (SE-CAD) in a biological sample from a mammalian subject, particularly in the urine, cervicovaginal fluid or blood. An increased level of expression of SE-CAD above the level of expression in the same sample of a healthy mammalian subject is an indication of a diagnosis of increased risk of PTB. Such diagnosis may further involve identify other clinical symptoms of PTB or PTL. Additionally the method may use additional biomarkers, such as fetal fibronectin.

The release by trichomonads of a hydrolase that hydrolyzes a narrowly defined class of substrates at a low pH without interference from hydrolases that are unrelated to trichomoniasis is the basis for a selective diagnostic assay for trichomoniasis that measures hydrolysis of any of these substrates by vaginal fluid at a low pH. Selective assays for trichomoniasis are also obtained by removing particulate matter from a sample of vaginal fluid to extract a fraction devoid of particles greater than a selected size, and where desired, combining the extracted fraction with any of certain specified hydrolase inhibitors, then testing the fraction for enzymatic hydrolase activity. These qualities of trichomoniasis are the basis for a series of diagnostic tests and test devices that produce results that are detectable by visual and other means with a high degree of accuracy.

Methods and systems for removing masking agents from test samples, e.g., DNA-containing samples obtained from living subjects, when they are submitted for or subjected to molecular assays. The present invention allows molecular assays of nucleic acids in bodily fluids and excretions, such as urine, blood, blood serum, amniotic fluid, spinal fluid, conjunctival fluid, salivary fluid, vaginal fluid, stool, seminal fluid, and sweat to be carried out with greater sensitivity.
