Vitamin B6 in Plasma / Whole Blood
Complete Kit, Order No. 26 000

 

Vitamin B6 consists of three vitamers: pyridoxine, pyridoxal and pyridoxamine. The metabolically active coenzyme form of vitamin B6 is pyridoxal-5'-phosphate (PLP). Signs of vitamin B6 deficiency mainly express in alterations of the skin, neurological disorders and anemias. Besides, a low vitamin B6 status may be responsible for an increase of the homocystein plasma level (hyperhomocysteinemia, see order no. 23000).

  • Excellent analytical sensitivity:
    0.4 µg/l

  • Quick and simple sample preparation

  • Injection interval: 10 min

  • Combineable with the test kits for vitamins B1 and B2
