  • Patent number: 8871521
    Abstract: Ketoacidosis is an extreme and uncontrolled form of ketosis, which is a normal response to prolonged fasting. Embodiments of this invention test the ketone level of a patient by measuring the ketone bodies in breath condensation. Some embodiments include a device for medical testing comprising a hollow container, comprising powder mixture of sodium nitroferricyanide, ammonium sulfate and silica and a liquid including an ammonium hydroxide solution.
    Type: Grant

  • Patent number: 5827749
    Abstract: Methods for determining the presence of a ligand in a sample suspected to contain the ligand are provided, along with apparatus suitable for performing the methods. The methods depend upon a color visualization indicating the ligand's presence or absence in the sample. Preferred methods comprise contacting the sample with colored particles which bear on their surface a receptor specific for the ligand, passing the sample/particle mixture through a filter, and then analyzing the color of the filtrate. The presence of ligand in the sample is established where the color of the filtrate is substantially different from the color of the receptor-bearing particles.

  • Patent number: 5231035
    Abstract: Methods for determining the presence of a first ligand, preferably a hapten, in a sample suspected to contain the first ligand are provided, along with reagent systems and apparatus suitable for performing the methods. The methods depend upon a color visualization indicating the presence or absence of the first ligand in the sample. Preferred methods comprise contacting the sample with a reagent system which comprises: (1) colored particles which bear on their surface a second ligand which may be the same as or different than the first ligand; and (2) an amount of a receptor which is specific for the first ligand and the second ligand, wherein the amount is sufficient to stabilize the particles. The methods further comprise passing the contacted sample and reagent system through a filter, and then analyzing the color of the filtrate. The presence of ligand in the sample is established where the color of the filtrate is substantially different from the color of the ligand-bearing particles.

  • Patent number: 4816415
    Abstract: A method for detecting cannabinoids in body fluids which comprises filtering body fluids through a cellulosic filtering means treated with a binding agent for cannabinoids and the filtering means. The binding agent is an arylcarboxylic acid. The cannabinoids are then treated with a subsequent reagent to produce a color reaction. A device for detecting cannabinoids is also disclosed which contains the filtering means treated with the binding agent so as to concentrate the cannabinoid prior to reaction with a suitable indicator.

  • Patent number: 4806487
    Abstract: A method for detecting basic narcotics or drugs in body fluids which comprises filtering body fluids through a cellulosic filtering means treated with a binding agent for the narcotics or drugs and the filtering means. The binding agent is a polycarboxylic acid. The narcotics or drugs are then treated with a subsequent reagent to produce a color reaction. A device for detecting basic narcotics or drugs in also disclosed which contains the filtering means treated with the binding agent so as to concentrate the narcotic or drug prior to reaction with a suitable indicator.

  • Patent number: 4331923
    Abstract: Circuitry is disclosed for measuring the quantity of total dissolved ionized salts in an undiluted aqueous sample. A bi-level power supply operating through a square wave generator and voltage follower creates a low amplitude AC signal at a predetermined level above a ground reference. The control voltage is applied through a conductivity probe assembly to two series connected operational amplifiers operating through a bridge assembly and meter movement to provide a reading of the total dissolved ionized salts in the sample as a function of their ionization characteristics.
