426 results about "Blood test" patented technology

A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test, are often grouped together into one test panel called a blood panel or blood work. Blood tests are often used in health care to determine physiological and biochemical states, such as disease, mineral content, pharmaceutical drug effectiveness, and organ function. Typical clinical blood panels include a basic metabolic panel or a complete blood count. Blood tests are also used in drug tests to detect drug abuse. In some of the United States, a blood test is required before marriage.

Blood coagulation test cartridge, system, and method

A system and method for determining a coagulation time, e.g., TT, PT, aPTT, and ACT, of a blood test sample deposited in a test cartridge is disclosed. A cartridge housing having upper and lower major sides and a minor sidewall encloses a test chamber having a test chamber pivot element and is provided with a cartridge port for introducing a test sample into the test chamber,. Ferromagnetic agitator vane leaflets extend from an agitator pivot element supported by the test chamber pivot element intermediate the upper and lower major sides for rotational motion. The agitator vane leaflets can be swept, in response to an external magnetic field, through the test sample in the absence of coagulation. A timer is started when the agitator movement is commenced whereupon the agitator moves freely. Resistance to agitator movement due to coagulation is detected, and the coagulation time is measured.

Blood test to monitor the genetic changes of progressive cancer using immunomagnetic enrichment and fluorescence in situ hybridization (FISH)

Amplification and overexpression of theHER-2 oncogene in breast cancer is felt to be stable over the course of disease and concordant between the primary tumor and metastases. Therefore, patients with HER-2 negative primary tumors will rarely receive anti-HER-2 antibody therapy. A very sensitive blood test is used to capture circulating tumor cells (CTC's) and evaluate their HER-2 gene status by FISH evaluation. The HER-2 status of the primary tumor and corresponding CTC's is used to assess the ratio of CTC's as a reliable surrogate marker. HER-2 expression of 10 CTC's is sufficient to make a definitive diagnosis of the HER-2 gene status for the whole population of CTC's in patients with recurrent breast cancer.

The related information ranges from identity information to biological product information. In each procedure of the blood collecting and supply workflow, the information is read / written by the computer into electronic tag and through the computer information network into the service management information system. The work flow of blood centers (stations), such as blood test reports before and after blood transfusions and the desired information of people and objects involved in blood transfusions, can thereby be recorded completely, integrally, precisely, and comprehensively by the RFID system.

Method of hemoglobin correction due to temperature variation

A method of measuring a hemoglobin parameter of a test sample of blood comprises diluting and lysing a test sample. Then, a temperature corresponding to the test sample is obtained. The diluted and lysed test sample is then delivered to a cuvette, and a spectrophotometer determines the absorbance and / or transmittance of the sample in the cuvette. With the absorbance and / or transmittance of the test sample, a first measurement of the hemoglobin parameter of the test sample is obtained. After a first measurement of the hemoglobin parameter is obtained, a processor determines a corrected measurement of the hemoglobin parameter of the test sample. The corrected measurement is a function of the measured temperature that corresponds to the test sample and the first measurement of the hemoglobin parameter. The method of measuring a hemoglobin parameter is valid over a range of test sample temperatures.
