DIAGNOSTIC PRODUCT AND IMMUNONEPHELOMETRY

摘要

PROBLEM TO BE SOLVED: To provide a diagnostic product capable of measuring up to the high concentration of a substance to be inspected without prozone and covering a wide concentration range of the substance and having a low minimum detecting concentration (high sensitivity) in the low concentration of the substance in a latex diagnostic product. SOLUTION: The diagnostic product comprises polymer particles (A) having a refractive index of 1.42 to 1.55 and polymer particles (B) having a refractive index of 1.57 to 1.65.
