Abstract: Provided are methods for determining the amount of thyroglobulin in a sample using various purification steps followed by mass spectrometry. The methods generally involve purifying thyroglobulin in a test sample, digesting thyroglobulin to form peptide T129, purifying peptide T129, ionizing peptide T129, detecting the amount of peptide T129 ion generated, and relating the amount of peptide T129 ion to the amount of thyroglobulin originally present in the sample.
Abstract: Methods are provided for detecting the amount of one or more CAH panel analytes (i.e., pregnenolone, 17-OH pregnenolone, progesterone, 17-OH progesterone, dehydroepiandrosterone (DHEA), androstenedione, testosterone, deoxycorticosterone, 11-deoxycortisol, and cortisol) in a sample by mass spectrometry. The methods generally involve ionizing one or more CAH panel analytes in a sample and quantifying the generated ions to determine the amount of one or more CAH panel analytes in the sample. In methods where amounts of multiple CAH panel analytes are detected, the amounts of multiple analytes are detected in the same sample injection.

Abstract: A method is provided for detecting the presence of nucleotides or monitoring nucleotide amplification. It utilizes fluorescence energy transfer by competitive hybridization. Competitive hybridization is achieved by using unequal length complementary probes which have a fluorophore on one probe and a quencher on the other. The fluorophore and quencher are juxtaposed in a manner wherein the proximity of the quencher to the fluorophore produces quenching of the fluorescence of the fluorophore.
Abstract: The invention disclosed herein is based on the identification of novel mutations in the JAK2 gene and JAK2 protein. The invention provides compositions and methods useful for diagnosing hematopoietic diseases including, for example, myeloproliferalive diseases. The invention also provides compositions and methods useful for determining a prognosis of an individual diagnosed as having a hematopoietic disease.
Abstract: The invention relates to the detection of vitamin D metabolites. In a particular aspect, the invention relates to methods for detecting derivatized vitamin D metabolites by mass spectrometry.
Abstract: Provided are methods for determining the amount of vitamin C in a sample using mass spectrometry. The methods generally involve ionizing vitamin C in a sample and detecting and quantifying the amount of the ion to determine the amount of vitamin C in the sample.
Abstract: In an exemplary embodiment, this invention provides a method of providing medical test results. The method includes a step of selecting formulary information that corresponds to a result of a medical test. The method also includes a step of generating a medical report. The medical report includes a laboratory report that corresponds to the medical test. The medical report also includes the selected formulary information.

Abstract: The invention relates to the administration of prescription drug formulary information. A list of drugs that a particular prescription drug plan will pay for in whole or in part is called a formulary. The invention involves the use of information and customizable rules associated with formularies, combined with information from patient medical records, to generate custom, dynamic formularies applicable to specific patients, groups of patients, or both. Depending on the choice of rules and the other information, this may help payers control prescription drug costs by encouraging the use of less-expensive drugs when medically appropriate, but without impairing the freedom of prescribers to prescribe specific drugs according to their professional judgments. Some embodiments may also be adapted to generate and store data about the use and functioning of the embodiments or aspects of them and to generate reports containing some or all such data in response to queries.

Abstract: The invention relates to sharing patient care information through electronic messaging. Systems for managing electronic health records may comprise extensive patient information, e.g., names, addresses, insurance coverage and/or other financial arrangements, health conditions, allergies, procedures undergone, and/or tests performed. The invention involves transfer of such information between users. Embodiments of the invention may pass such information by adding to electronic messages pointers that uniquely refer to one or more patient records. Some embodiments may thereby send health information electronically while preserving metadata and/or other meaning associated with the data.
