Abstract: The invention relates to a microfluidic system comprising a microfluidic device having a first and a second opposite surfaces and an optical detector, the microfluidic device comprises a flow channel with a detection channel section having a length of at least about 1 mm, the microfluidic device comprises at least one aperture section comprising at least a part of said detection channel section and a transparent window into said detection channel section, the optical detector is arranged to determine at least one optical property of said aperture section as a function of time. The flow channel may have capillary dimensions and/or it may wholly or fully be arranged to drive a fluid flow by applying external forces. The microfluid device may be used to determine various properties of a sample fluid, for example it may be used to determine a samples coagulation properties and/or reactions of one or more components in a fluid sample as a function of time.

Abstract: A microfluidic device comprising at least one test channel, which test channel comprises an upper test channel section with an upstream end and a sampling region at its upstream end and at least one reference channel, which reference channel comprises an upper reference channel section with an upstream end and a sampling region at its upstream end. The test channel and the reference channel comprise a merging region downstream to the upper test channel section and a common downstream channel section. The merging region and the common downstream channel section are arranged such that a reference liquid flowing from the upper reference channel section into the merging region will block a test liquid flow in the upper test channel section when the test liquid flow has not yet reached the merging section. The microfluid device may be used for detecting change of flow properties e.g. due to agglomeration, agglutination or viscosity change in a liquid preferably selected from water, urine, blood, or blood plasma.

Abstract: A microfluidic device comprising a flow channel with an inlet and a gas escape opening is described. The flow channel comprises a liquid flow channel section and a flow controlling section downstream to the liquid flow channel section and upstream to or coinciding with the gas escape opening. The flow controlling section provides a flow resistance to gas, which is sufficiently high to reduce velocity of a capillary flow of a liquid in the liquid flow channel section. The microfluidic device with the flow controlling section provides a device in which the velocity of the flow can be reduced to a desired level. Also is described a method of performing a test using the microfluidic device.
