Novel Testing Procedures for Detection of Primary Humoral Immunodeficiency

After consent is obtained, blood will be obtained. The total amount of blood to drawn in one day will not exceed 1.5 mL (1/3 tsp) per pound of body weight. All samples will be collected at the same time as routine blood draws as ordered by your physician. Subject samples will be de-identified by the Principal Investigator (PI) and given a serial number. The PI will retain a secured log of the serial numbers and basic identifiers (name, Date of Birth (DOB0, sex, preliminary diagnosis, and test results), and the subject samples will be stored in a secured freezer. Only the PI will have access to the secured log book. All study test results will be kept on compact discs, or similar computer storage devices, in a secured area that will only be accessible by the PI. Study test results will not kept on computers accessible by other individuals. The samples will not be sold to any third party. The results of this research will not be conveyed to any third party. If the subject withdraws or is withdrawn from the study all identifiable biological samples from that subject will be discarded. The sample will not be available for any other type of testing outside of this study.
