Oral fluid for drug testing has several advantages over other specimens: (1) It may be collected noninvasively and under direct supervision; (2) its drug concentration reflects blood-drug concentrations; and (3) it can be processed by conventional drug screening and confirmation methods. This technology provides a system that measures the quantity of a drug (without needing a priori knowledge of the drug) in an oral fluid specimen and translates this level to a blood plasma drug concentration. The method first measures the concentration of a drug in an oral fluid sample. Next, a processor calculates the blood plasma concentration from the measured oral fluid drug concentration. Finally, this blood plasma drug level is utilized to calculate a total body drug concentration.

There is disclosed a self-adhesive moisture control label (10) for product packaging, comprising: a water absorbent layer (14) capable of absorbing water; and an adhesive layer provided such that the label (10) can be adhered to the packaging. The moisture control label (10) is capable of controlling the humidity of the atmosphere within the packaging. There is also disclosed a method of manufacturing a moisture control label (10).
摘要:
Disclosed are probes, systems, and devices that can be used to assay the presence of a biomarker in the sinus of a patient. The probes, systems, and devices can be used to contact the sinus fluid inside the sinus of a patient with an immunoassay for the presence of a biomarker that is characteristic of sinusitis. The probes can therefore be used to determine the underlying cause of sinusitis in a patient. Also provided are methods of treating sinusitis by administering to a patient a therapeutic regimen selected in view of a biomarker detected in the sinus of the patient. As the biomarker is associated with one or more causative agents of sinusitis, a therapy effective to treat the underlying causative agent can be selected.
摘要:
In accordance with one embodiment of the present disclosure, a diagnostic test kit for detecting the presence or absence of nitrites within a test sample is disclosed. The test kit comprises an aromatic primary amine that is capable of reacting with a nitrite to form a diazonium ion. The test kit also comprises a lateral flow device that comprises a chromatographic medium and an absorbent material that receives the test sample after flowing through the chromatographic medium. The chromatographic medium defines a detection zone within which is contained a detection reagent consisting of a nucleophilic aromatic amine that is directly bound through covalent bonding to the chromatographic medium. The detection reagent is capable of reacting with the diazonium ion to form an indicator (e.g., azo compound). The indicator exhibits a color that is different than the color of the detection reagent.
摘要:
A drug test device for bodily fluids, such as urine, includes a cup and a removable lid which houses one or more test strips. The lid is releasably locked onto the cup so as to align dipping ends of the test strips exposed through an underside of the lid with a position stabilizer, thereby causing the dipping ends to be located downwardly and submerged in fluid when the device is placed on its side in a reactive position. The position stabilizer may comprise a sidewall indentation that reduces the internal volume of the cup and keeps the cup from rolling when placed on its side.
摘要:
The present invention includes compositions, methods, and systems for the analysis of skin and hair conditions. The system includes a method and apparatus for analyzing skin and hair samples by taking a sample, identifying desired components of the sample, obtaining an image electronically, storing the image, and analyzing the image using analysis software.
摘要:
The invention relates to an assay and a kit for the determination of the status of the fibrinolytic system. In particular the invention relates to a method for the determination of the status of the fibrinolytic system from tear fluid samples. Additionally the invention relates to a sterilized, calibrated capillary equipped with a plastic balloon, suitable for tear fluid sampling, and a kit for the assessment of the status of the fibrinolytic system, or for the determination of its balance, comprising a sampling capillary, reaction sheets, color scale to help the evaluation, and reagents.
