Green (Sodium or Lithium Heparin), Lavender (EDTA), Pink (K2 EDTA), Plasma Separator Tube (PST), Serum Separator Tube (SST), or Plain Red.

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.

Storage/Transport Temperature

Frozen.

Unacceptable Conditions

Whole blood. Specimens not protected from light. Icteric specimens.

Synonyms

  • Pyridoxal Phosphate (Vitamin B6 (Pyridoxal 5-Phosphate))
  • P 5-P
  • Pyridoxal Phosphate

Notes

This test measures pyridoxal 5-phosphate, the biologically active form of vitamin B6.

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.
