Technology
Technique of electron microscopy in which the specimen is coated with heavy metal and then scanned by an electron beam. The resolution is not as great as with transmission electron microscopy, but preparation is easier (often by fixation followed by critical point drying), the depth of focus is relatively enormous, the surface of a specimen can be seen (though not the interior unless the specimen is cracked open) and the image is aesthetically pleasing.
Technology
An electron microscopy imaging technique that is utilized to examine structural components of a sample by passing electrons through the specimen.
Tests
The determination of the amount of 2-hydroxyfluorene a biological specimen.
Tests
The determination of the amount of 8-iso-prostaglandin F2 alpha in a biological specimen.
Tests
The determination of the ratio of the 8-iso-prostaglandin F2 alpha to creatinine in a biological specimen.
Tests
The determination of the amount of activated lymphocytes in a biological specimen.
Indicators
A measurement of the length of time that it takes for clotting to occur when activating reagents are added to a plasma specimen. The test is partial due to the absence of tissue factor (Factor III) from the reaction mixture.
Tests
A measurement of the resistance in the anticoagulation response to activated protein C in a biological specimen.
Tests
A measurement of the Alternaria tenuis alternata antigen IgG antibody in a biological specimen.
Tests
A measurement of the American cockroach (Periplaneta americana) antigen IgA antibody in a biological specimen.
Tests
A measurement of the American cockroach (Periplaneta americana) antigen IgG antibody in a biological specimen.
Tests
A measurement of the American cockroach (Periplaneta americana) antigen IgG4 antibody in a biological specimen.
