  • Turnaround Time: 24 hours (immunoassay), 5 working days (mass spec)
Theophylline

Theophylline

Reference Range

Therapeutic range: 10-20 mg/L (Pre-dose)

  • Minimum time for patient to reach steady state without loading or after dosage change is 2 days
  • Turnaround Time: 24 hours
Thiopurine S-Methyltransferase (TPMT)

Thiopurine S-Methyltransferase (TPMT)

Reference Range

 

TPMT phenotype/activity reference ranges:

  • <6 nmol/ghb/hr = Deficient
  • 6-34 nmol/gHb/hr = Low
  • 35-79 nmol/gHb/hr = Normal
  • >79 nmol/gHb/hr = High

TPMT genotype classifications:

  • WT = wild-type, normal result
  • H3 = TPMT 1*/3* - heterozygous for TPMT, this would indicate a reduced activity.  Advise reduce dose of azothioprine.
  • H2 = TPMT 1*/2* - heterozygous for TPMT, this would indicate a reduced activity.  Advise reduce dose of azothioprine
  • H03 = TPMT 3*/3* - homozygous for TPMT, this would indicated deficient TPMT activity.  Advise stop treatment with azothioprine.
  • H02 = TPMT 2*/2* - homozygous for TPMT, this would indicated deficient TPMT activity.  Advise stop treatment with azothioprine.
  • Turnaround Time: 14 days
Thrombin Time

Thrombin Time

Reference Range
