Abstract: What is disclosed is a method for creating a database for determining a virtual reference value for a light transmission aggregometry measurement, comprising the following steps:



a. providing platelet-rich plasma “PRP” (17) of a reference blood sample;
b. performing a light transmission measurement with a first light wavelength and a second light wavelength (14), different from the first, on the PRP (17) of the reference blood sample;
c. providing platelet-poor plasma “PPP” of the reference blood sample;
d. performing a light transmission measurement on the PPP in order to determine a PPP reference value;
e. assigning the measurement result of step d to the measurement results of step b in a database;
f. repeating steps a to e for a plurality of reference blood samples.




The database obtained using this method makes it possible to determine a virtual reference value that is an excellent estimate of the PPP reference value. Once the database has been created, it is possible to determine virtual reference values of blood samples to be examined and perform LTA measurements using the virtual reference values, without the need to obtain PPP from the blood samples to be examined.

Abstract: A time response measurement apparatus includes a pulse formation unit, an attenuation unit, a waveform measurement unit, and an analysis unit. The pulse formation unit generates first pulsed light including a wavelength of pump light, second pulsed light including a wavelength of probe light, and third pulsed light including the wavelength of the pump light and the wavelength of the probe light, on a common optical axis. The attenuation unit transmits the first pulsed light, the second pulsed light, and the third pulsed light output from a sample arranged on the optical axis after being incident on the sample. An attenuation rate for the pump light is larger than an attenuation rate for the probe light. The analysis unit obtains a time response of the sample based on temporal waveforms of the first pulsed light, the second pulsed light, and the third pulsed light having passed through the attenuation unit.

Abstract: An optical well is configured to receive a test sample for examining an optical characteristic of the sample at a first wavelength in a predetermined wavelength range. The optical well includes a wall having a bottom wall portion and a sidewall portion defining a chamber for receiving the test sample, and an optical film formed into a shape so that a portion of the sidewall portion includes a first portion of the optical film, and a portion of the bottom wall portion includes a second portion of the optical film. For a normally incident light, the microlayers in each of the first and second portions have an average optical reflectance of greater than about 80% in the predetermined wavelength range. The forming results in the plurality of microlayers of the integral formed optical film having a thinnest portion and a thickest portion having a thickness difference of at least 30%.
