In-vitro diagnostic
View Patent ↗An in-vitro diagnostic includes a housing, a storage, and a blocking agent. The housing houses a liquid including a test substance included in a sample extracted from a subject. The storage stores a substance that specifically reacts with the test substance. The blocking agent is placed to separate the container and the storage.
1. An in-vitro diagnostic comprising:
a housing for a liquid comprising a test substance contained in a sample extracted from a subject;
an optical waveguide as a support;
a substance layer, on the optical waveguide, that stores a substance that specifically reacts with the test substance and a first blocking agent that supports the substance, wherein the substance is bound to a surface of the optical waveguide; and
a dry film comprising a soluble coating agent and a second blocking agent separating the housing and the substance layer, wherein the dry film covers a surface of the substance layer, wherein the dry film does not contain a substance that specifically reacts with the test substance, and wherein the second blocking agent is different from the first blocking agent.
2. The in-vitro diagnostic according to claim 1 , wherein the second blocking agent is dispersed into a soluble coating agent included in the dry film.
3. The in-vitro diagnostic according to claim 1 , wherein the second blocking agent is covered by a lipid film and is dispersed into a soluble coating agent included in the dry film.
4. The in-vitro diagnostic according to claim 1 , wherein the second blocking agent is covered by a lipid film and is attached on an upper surface of the dry film.
5. The in-vitro diagnostic according to claim 1 , wherein the second blocking agent is selected in accordance with a measurement item.
