Abstract
The invention relates to a method and to a diagnostic agent for detecting hemostasis disturbances, wherein, as a consequence of blood platelet aggregation, clot formation and/or clot dissolution, substances are brought to a distance from each other which permits or prevents an interaction, in particular an energy transfer, between the substances, and the extent of the interaction is measured.
Claims55
A method for detecting a disturbance of hemostasis, comprising:
- 1) providing
- A) a sample to be tested and
- B) at least two primary substances which can enter into interaction with each other when in spatial proximity,
- wherein the interaction directly or indirectly provides a signal which correlates with the extent of interaction between said primary substances, and
- wherein at least one of the at least two primary substances is able to bind nonspecifically to components of a blood clot,
- 2) measuring the signal, and
- 3) correlating the signal with the degree of platelet aggregation, clot formation and/or clot dissolution in the sample.
A method for detecting clot formation or dissolution comprising:
- 1) providing a sample to be tested, a photosensitizer, and a chemiluminescent compound;
- wherein the photosensitizer and the chemiluminescent compound are brought into close proximity due to clot formation;
- and
- wherein the chemiluminescent compound is activated by singlet oxygen;
- and
- wherein at least one of the photosensitizer or the chemiluminescent compound is able to bind nonspecifically to components of a blood clot;
- 2) activating the photosensitizer to generate singlet oxygen;
- 3) detecting a signal related to the activation of the chemiluminescent compound by the singlet oxygen;
- and
- 4) correlating the signal to the degree of clot formation or dissolution in the sample.
A method for detecting clot formation or dissolution comprising:
- 1) providing a sample to be tested and at least two primary substances which can enter into interaction with each other when in close proximity,
- wherein said interaction produces a signal;
- wherein the at least two primary substances are brought into close proximity due to clot formation;
- and
- wherein formation of a clot brings the at least two primary substances into spatial proximity;
- and
- wherein at least one of the at least two primary substances is able to bind nonspecifically to components of a blood clot;
- 2) measuring a signal produced by the interaction of the at least two primary substances;
- and
- 3) correlating the signal to the degree of clot formation or dissolution in the sample.
