Considerations Regarding Clinical Specimens

Finally, the type of clinical specimens available will determine the choice of the typing method. The majority of the techniques mentioned can be performed with any type of clinical material (Table 1). An exception is the HC2 test (Digene), the manufacturer of which recommends the use of a dedicated specimen collection medium for cervical and vaginal swabs. These samples can also be used for PCR, but only after DNA isolation because organic solvents in the Digene- and other cell-preserving media will inhibit PCR. In archival material (smears on slides or formalin-fixed, paraffin-embedded material), the DNA is usually degraded to fragments <200 base pairs. This renders them unsuitable for PCR-based methods that generate products of >200 base pairs.

Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
