ABSTRACT:
An apparatus for testing body fluid or blood electrolytes in a body fluid or blood serum sample includes three testing stations. The blood sample is automatically transported from an input point serially and in a linear manner along a track past the three testing stations to an output point. The first testing station removes a first portion of the sample at a first location along the track and has a rotating structure including a container which receives and stores the first portion and rotates it to a first testing position at a first time. A testing structure tests the first portion while at the first testing position at that first time.
The second testing station removes a second portion of the sample at a second location along the track and includes a second rotating structure including a container which receives and stores the second portion and rotates the stored second portion to a second testing position, also at the first time. A second testing structure tests the second portion while at the second position at the first time.
A third testing station removes a third portion of the sample at a third location along the track and tests the removed third portion at the noted first time so that all the tests are performed simultaneously and the results thereof can be derived simultaneously without the need for memory, delay or control apparatus.
