Testmedica lateral flow tests are also called immunochromatiographic strip
(ICS) tests. They have been a popular platform for rapid tests since their
introduction in the late 1980's.
Testmedica ICS tests are used for the specific qualitative or
semi-qualitative detection of many analytes including: antigens, antibodies,
and even the products of nucleic acid amplification tests. One or several
analytes can be tested for simutaneously on the same strip. Urine, saliva,
serum, plasma, or whole blood can be used as specimens. Extracts of
individuals exudates or fluids have also been successfully used.
Test sensitivity can be quite good. For example, hepatitis B
surface antigen (HBsAG) UCS tests claim a sensitivity of 1.0 ng HBsAG/ml or
less. Test specifically can also be very high. The tests use colloidal gold,
dye, or latex bead conjugates to generate a signal. The assenbled strips are
dried and packaged, making them stable for months when properly protected from
moisture and excessive heat.
To preform the test--a sample--either used alone or with an extract
reagent or running buffer--is placed on the sample pad on one end of the
strip. The signal reagent is solubolized and binds to the antigen or antibody
in the sample and moves through the membrane by capillary action. If specific
analyte is present, the signal reagent binds to it, and a second antibody or
antigen-immobilized as a line in the nitrocellulose--then captures the
complex. If the test is positvie a pink/purple line developes.
Once the specimen is added, the tests can be left unattended until they
are read. The tests can be run individually or in limited-size batches.
Test and test results are for informational purposes
only and are not intended to monitor, treat, or diagnose any disease. Only
your pyhsican can diagnosis disease. Home Scan, Home Screen pH Acid monitor
and Diet Check Ketone Stix urine reagent strips are diagonistic tools but are
used to detect levels of specific parameter. The detection of those parameters
and the levels may be indicative of an abnormallity or infection. Always rely
upon your health care provider to detect, for diagnosis, and treat any
infection or abnormality. If results are unexpected, contact your health care
provider.
