Abstract: A method of ensuring the security of data from a medical test includes providing the patient with a medical data card issued by a secure information provider, and having a unique patient identification number (PID), a public key encryption private key, and public key encryption public key (Key 2). The method further includes a first test request card having an encrypted identification of the patient and the test, a health care provider code, Key 2, and the test type that accompanies the patient's test specimen to the secure information provider, a second test request card bearing an encryption of the PID and the test type to forward with the patient's specimen to a testing laboratory; a first test results card bearing an encryption of the PID and the results; and a second test results card that may be read in conjunction with the patient's medical data card.

Abstract: Methods for detecting variant genes having a polymorphism associated with reduced metabolism of a substrate selected from the group consisting of a CYP3A4 substrate, a CYP3A5 substrate and a GSTM1 substrate in an individual are disclosed. The methods are genotyping methods to identify specific polymorphisms which have been found to be associated with reduced metabolism of chemotherapeutic agents, such as cyclophosphamide and BCNU. Also disclosed are novel polymorphic nucleic acid molecules useful in the methods of the invention.
