DIAGNOSTIC TEST STRIP HAVING FLUID TRANSPORT FEATURES
First Claim
1. A test strip for testing a fluid sample, comprising:
- a strip with a first major side for positioning facing a fluid sample;
a capillary channel having a mouth and having a measurement site;
a fluid transport path on the strip terminating at the mouth of the capillary channel;
a depending portion at an end of the fluid transport path opposite the mouth of the capillary channel extending away from the strip whereby a droplet of fluid sample contacting the depending portion is directed to the mouth of the capillary channel.

Abstract
A test strip for testing a blood sample is provided with a fluid transport feature to facilitate transport of a blood sample obtained from a lancing operation through a capillary channel to a measurement site. A fluid transport path is defined on the major face of the strip terminating at the mouth of the capillary channel. The fluid transport path includes a depending portion at one end opposite the mouth of the channel. The depending portion extends away from the strip on the side facing the fluid sample, such that a droplet of fluid sample contacting the depending portion is directed toward the mouth of the capillary channel. Thereafter the sample moves by capillary action to the measurement site.
