Green (Sodium or Lithium Heparin), Lavender (EDTA), Pink (K2 EDTA), Plasma Separator Tube (PST), Serum Separator Tube (SST), or Plain Red.
Additional Requirements
Collect: GREEN LI HEP
Auto Lab Accepts:
Unacceptable Conditions
Whole blood. Specimens not protected from light. Icteric specimens.
Specimen Preparation
Separate plasma or serum from cells, protect from light and transfer 1 mL plasma or serum to an ARUP Amber Transport Tube within 1 hour of collection. (Min: 0.5 mL) Separate light-protected specimens must be submitted when multiple tests are ordered.
Ordering Recommendations
Use for nutritional assessment of vitamin B6.
Storage/Transport Temperature
Frozen.
Stability (from collection to initiation)
After separation from cells: Ambient: 3 Hours; Refrigerated: 1 week; Frozen: 2 months
Performed
Sun-Sat
Reported
1-5 days
Notes
This test measures pyridoxal 5-phosphate, the biologically active form of vitamin B6.
Lab info
Specimens are sent by the Core Laboratory to ARUP Laboratory.
Section
Reference Laboratory-ARUP Laboratories
Reference Laboratory Test Code
0080111
Methodology
Quantitative Liquid Chromatography-Tandem Mass Spectrometry
Synonyms
P 5-P
Pyridoxal Phosphate
Reference Interval
20-125 nmol/L
Interpretive Data
Pyridoxal 5'-phosphate measured in a specimen collected following an 8 hour or overnight fast accurately indicates vitamin B6 nutritional status. Non-fasting specimen concentration reflects recent vitamin intake.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
