LIMITATIONS OF PROCEDURES
7.1 QBC CENTRIFUGAL HEMATOLOGY TESTS
QBC tests should be performed at temperatures between 20 and 32 ºC (68 and 90 ºF).* If tubes are run at
temperatures below 20 ºC, test results may be erroneously high; if tested above 32 ºC, interfaces may become
blurred and difficult to detect visually or automatically, depending on the model of QBC analyzer performing the
test.
7.2 QBC MALARIA TEST
The QBC Malaria Test is a qualitative method for diagnosing “positive” or “negative” patients. While numerous
reports have demonstrated that the QBC Malaria Test is significantly more sensitive for detecting malaria than
stained blood films, the QBC Test may not detect very low levels of parasitemia.
Experienced microscopists can discriminate between various species of malarial parasites using the QBC Malaria
Test. Examination of a thin blood smear may be required to differentiate species in some cases.
See the QBC Malaria Test package insert for a list of literature references.
*IMPORTANT: For room temperature specifications: consult the package insert of the disposables in use in your
laboratory.
