The invention involves the monitoring of a biological parameter through a compact analyzer. The preferred apparatus is a spectrometer based system that is attached continuously or semi-continuously to a human subject and collects spectral measurements that are used to determine a biological parameter in the sampled tissue. The preferred target analyze is glucose. The preferred analyzer is a near-IR based glucose analyzer for determining the glucose concentration in the body.

A method and apparatus are provided for noninvasive sampling. More particularly, the method and apparatus relate to control of motion of an optical sample probe interface relative to a tissue sample site. A dynamic probe interface, is used to collect spectra of a targeted sample, control positioning of the sample probe relative to the tissue sample in terms of at least one of x-, y-, and z-axes, and/or control of sample tissue displacement to minimize spectral variations resulting from the sampling process and increase analyte property estimation precision and accuracy.
Method and apparatus for communicating with a sealed electronic device via the electronic device's existing data ports for programming, testing configuration or diagnosis of the electronic device such as a transmitter unit for use in a data monitoring and management system such as analyte monitoring and management system is provided.
A skin penetrating system is provided with a drive force generator and a disposable housing member. A plurality of penetrating members are positioned in the disposable housing member. Each penetrating member is coupled to the drive force generator. A plurality of analyte detecting members are each associated with a penetrating member and are positioned in the disposable housing member. Each analyte detecting member is positioned in a sample chamber. The sample chambers have openings for transport of a body fluid into the sample chamber. Each analyte detecting member is configured to determine a concentration of an analyte in a body fluid. A user interface is configured to relay at least one of, skin penetrating performance or a skin penetrating setting.
A blood testing apparatus includes a device for withdrawing blood, a membrane-type testing element, an evaluating device, and a display device forming a complete system which can be manipulated as a single piece of apparatus. Multiple testing elements can be inserted into the apparatus and brought successively to a work position for carrying out several measurements. The blood withdrawing device includes multiple pricking elements. One pricking element is pushed through one testing element and pricks the surface of the skin of a user. The pricking position is disposed so that blood withdrawn from the surface of the skin can impinge upon the testing element.
