What is a Tegretol blood test?

A Carbamazepine Blood Test is a test that evaluates the blood levels of carbamazepine. It is used in the dose adjustment and to ensure that carbamazepine levels remain within an acceptable range.

What is a normal Tegretol level?

Results are given in micrograms per milliliter (mcg/mL) or micromoles per liter (micromol/L). Safe blood levels of carbamazepine are 4 to 12 mcg/mL, or 17 to 51 micromol/L. You may have seizures, low blood pressure or fall into a coma if your levels are above 40 mcg/mL, or 170 micromol/L.

What happens if Tegretol level too low?

If the level is too low, the drug may not be effective and the person may experience a recurrence of symptoms (i.e., seizures, mania, or pain); if the level is too high, the person may experience toxic side effects.

What happens if your Tegretol level is too high?

It causes dizziness, imbalance, drowsiness, coma, and generalized seizures. It can cause abnormal cardiac conduction that can lead to arrhythmia. It has been reported that acute carbamazepine toxicity could be associated with the presence of spindle coma on EEG.

What labs should be monitored for Tegretol?

ONGOING MONITORING: Baseline labs: urine pregnancy, platelets, reticulocytes, serum iron, CMP. Monitoring of blood levels is recommended with the usual adult therapeutic drug levels between 4 and 12 mcg/mL.

Do you check Tegretol levels?

When checking carbamazepine levels in a patient on a regular medication regimen, the specimen should be drawn immediately prior to next carbamazepine dose (trough).

Does Tegretol show up on a drug test?

Prescription drugs, over the counter medications and herbal supplements may also cause false positive screening results. False positive THC reactions are most commonly associated with Clozaril, Propulsid, Protonix, Paxil, Tegretol and Zocor.

What lab results indicate an adverse reaction to carbamazepine?

The complete blood cell count (CBC) with a differential should be obtained. Rarely, hematologic adverse effects, including agranulocytosis, thrombocytopenia, and aplastic anemia, have been reported with long-term carbamazepine use.

Why do you test for carbamazepine?

The carbamazepine blood test is requested to check the amount of carbamazepine in the blood and determine whether drug concentrations are in the desired (“therapeutic”) range. Initially, the test may be used to establish the appropriate dose for a particular individual.

How do you check carbamazepine levels?

A steady state concentration is reached 2 to 4 weeks after initiating therapy. A trough level should be drawn immediately before the next dose. The therapeutic range is 4 – 12 ug/mL as measured by fluorescence polarization immunoassay. Toxicity may occur in the 8.0?

Do you need blood tests with carbamazepine?

The carbamazepine blood test is requested to check the amount of carbamazepine in the blood and determine whether drug concentrations are in the desired (“therapeutic”) range. Initially, the test may be used to establish the appropriate dose for a particular individual.
