Locations and Service HoursGeneral InformationThe patient must be positively identified when the blood specimen is collected. Identification of the patient is crucial to ensuring that the blood specimen is drawn for the correct patient. The likelihood of error occurring in the area of collecting and handling specimens is probably greater than the likelihood of error occurring in the procedure itself. Much attention needs to be devoted to the process of collecting and handling specimens. Assemble the necessary supplies for the Vacutainer®. The evacuated tube system is the most commonly used means of collecting specimens. This system is preferable to the needle and syringe since it allows the blood to pass directly from the vein to the evacuated tube. The evacuated tube system decreases the possibility of needlesticks, helps to eliminated some labelling errors and decreases the likelihood of inappropriate specimens. It is important to not leave the tourniquet on for longer than one minute; to do so may result in either hemoconcentration or variation in blood test values. For accurate test results, follow the proper Vacutainer® draw order. The following is an example of the most common draw order:
Also, to eliminate tissue fluid contamination, it is suggested that 3 to 4cc of blood be drawn into sodium citrate tubes (blue) before filling sodium citrate tubes (blue). Some tests require that blood specimens be cooled in ice water, placed in warm water, or protected from light immediately following the venipuncture in order to prevent metabolic processes which may cause alteration of some test values. Specimen handling instructions are included in the test list in this manual. Use "universal precautions" at all times. WITHOUT capping needles, dispose of the puncture unit in an appropriate Sharpes container. Bag each specimen as required by Infection Control policies and place in laboratory courier box at the nursing station. Phlebotomy ServiceThe laboratory phlebotomy team makes routine adult and pediatric blood drawing rounds 7 days a week at 0500 and 1900. Nursery rounds are at 0600. Laboratory phlebotomist are not available to procure STAT or Timed specimens. Laboratory phlebotomist are instructed to procure specimen from properly identified patients only. A list indicating patients drawn or attempted and specimens collected is left at each nursing station. Accession logs for specimen collected in our outpatient laboratories are kept at each of the blood drawing stations. Clinical laboratory results can be obtained by contacting the Specimen and Report Center at 4-0500, 24 hours a day and 7 days a week. The patient's medical record number and the patient's full name are necessary in order to obtain clinical results. Phlebotomy Specimen ContainersSIZE STOPPER COLOR ADDITIVE
Minimum Blood Amounts RequiredICU CONDENSED LIST
PEDIATRICS/SELECTED ADULTS These minimums are assuming a Hct of <45-50%. If the Hct is >50% of the minimum amounts to be collected in bullets, then red tops and Microtainers® must be increased to obtain the minimum serum amounts for the test. The ones to look out for are children less than 1-2 months of age and children with heart problems. These children may tend to have a Hct of >50%. Neonatal Requirements, where different from adult minimums, are listed under the alphabetical listing of analytical methods. If there are any questions, call Pathology (ext. 2525) or SARC (ext. 4-0500) to double-check the minimum before attempting a draw.

Which of the following blood collection tube tops would contain a serum separator gel?Gold-top serum separator tube (SST)
This tube contains a clot activator and serum gel separator – used for various chemistry, serology, and immunology tests.
Which laboratory section would most likely perform the test on a specimen collected in an SPS tube?Blood collection eq.. What is the most most important step in specimen collection?1. Planning ahead. This is the most important part of carrying out any procedure, and is usually done at the start of a phlebotomy session.
