2.3 Phlebotomy Guideline
1. Insert the ESR-Vacuum Tube into the plastic holder
(Figure 5a). Hold the tube so the cap is flush against the
needle holder as the sample is collected.
2. Angle the tube so the blood stream hits the tube wall
before mixing with the citrate solution to minimize the
formation of bubbles.
3. Watch for an air bubble to rise in the sample as the tube
fills to indicate the draw is complete and remove the tube
immediately.
4. The ideal fill level and acceptable fill range are indicated
on the tube.
• 1.2ml ESR-Vacuum Tubes: 60mm ± 5mm
• 2.0ml ESR-Vacuum Tubes: 100mm ± 8mm
5. It is especially important to mix Streck ESR-Vacuum
Tubes thoroughly by inverting a minimum of 8 times due
to their smaller tube diameter and draw volumes (1.2ml
and 2.0ml) compared to an EDTA tube (Figure 5b).
6. Prior to analysis, thoroughly mix the sample again.
Rotate the tubes on the ESR-657 Mixer for a minimum
of three minutes, or hand-mix a minimum of 8 complete
inversions.
7. Samples can be maintained from the time of blood
collection for up to 72 hours prior to analysis when
transported and stored at 2-10° C, or up to 4 hours at 18-
30° C.
8. Refer to the ESR-Vacuum Tube Instructions For Use
(IFU) for more details.
Important: The mixing procedure is very
important! If the citrate is not properly mixed with
the blood, clots/aggregates may form and cause a
falsely elevated result.
2.4 Mixing a Sample
Samples must be thoroughly mixed prior to analysis. The
ESR-657 Mixer is an optional accessory designed to
accompany the ESR-Auto Plus (Figure 6). The automated
mixer holds up to 10 ESR-Vacuum Tubes at one time.
1. Place the mixer on a level surface.
2. Stop the mixer to remove or add tubes. Gently snap ESR-
Vacuum Tube samples into the numbered slots on the
mixer (Figure 6).
3. Locate the power switch on the top of the mixer to turn
the unit “on.”
4. The ESR-657 Mixer operates using a slow 360° rotation
to ensure complete mixing.
5. Allow the samples to rotate for a minimum of 3 minutes
before analyzing.
