Follow the manufacturer's recommendations on properly setting the needle. What should I do? Ansari-Lari M, Kickler TS, Borowitz MJ. Use: EDTA plasma for molecular diagnostic tests (eg, polymerase chain reaction (PCR) and/or branched DNA amplification (bDNA) techniques). Note: If the blood has to be mixed with an additive (gently invert the tube 4 to 10 times depending on the specimen tube being used), this must be done immediately after collection. These are easily identified by the yellow diagonal stripes on the label. Rouleaux of the red cells (stacking like piles of coins) and platelet clumping will also occur.

Put on laboratory personal protective equipment. Failure to push the spreader slide completely across the flat slide. Turn the centrifuge off, if not an automatic turn off, and allow it to come to a complete stop. They found that a BNP value >80 pg/mL could be used to identify patients with CHF from this population with a sensitivity of 97%, specificity of 98%, positive predictive value of 92%, and a negative predictive value of 98%.6.
