Laboratory studies

The following laboratory studies are indicated in the pretransplant evaluation of all patients awaiting solid organs [2, 3] :

  • Serum calcium level
  • Phosphorus level
  • Bicarbonate level
  • Alkaline phosphatase level
  • Blood urea nitrogen (BUN)/creatinine levels
  • Intact parathyroid hormone (PTH) assay, to assess for hyperparathyroidism (primary or secondary)
  • 25-Hydroxyvitamin D value to assess total body vitamin D stores
  • Thyroid function tests (eg, thyroid-stimulating hormone, free levothyroxine)
  • Testosterone level (males only), to ensure eugonadism
  • Estradiol and follicle-stimulating hormone (FSH) levels (in females with amenorrhea or irregular cycles)
  • Magnesium level
