When working with individuals diagnosed with bipolar affective disorder, understanding and ordering the correct baseline labs for bipolar disorder is critical in ensuring patient safety and optimal treatment. As psychiatric nurse practitioners, we often encounter challenges in interpreting lab results, but doing so plays a vital role in prescribing safely and ruling out underlying medical conditions.

What Baseline Labs Should You Order for Bipolar Disorder?

One common question is: What baseline labs should be ordered for a patient diagnosed with bipolar affective disorder?

Consider the following options:

  • A. CMP (Complete Metabolic Panel), TSH, free T4, prolactin level
  • B. CBC w/differential, CMP, TSH, free T4, Vitamin D, lipid panel
  • C. Lipid panel, BMP (Basic Metabolic Panel), CBC w/differential

Did You Get the Answer Right?

If you selected B, you’re correct! The recommended baseline labs for bipolar disorder include a Complete Blood Count with differential, Complete Metabolic Panel, TSH, free T4, Vitamin D, and lipid panel. These labs allow providers to assess medical conditions that may impact psychiatric symptoms and ensure safe prescribing.

  1. Assess General Overall Functioning
    • By ordering baseline labs for bipolar disorder like CMP and CBC w/differential, psychiatric nurse practitioners can gain insight into the patient’s overall health and organ function, ensuring the body is functioning as intended.
  2. Rule Out Medical Conditions
    • Certain medical conditions like hyperthyroidism or vitamin deficiencies can mimic or worsen psychiatric symptoms. For example, abnormal TSH and free T4 levels may reveal thyroid dysfunction that could impact mood regulation.
  3. Prescribe Safely
    • Baseline lab results help avoid adverse effects, such as QTc prolongation causing cardiac arrhythmias. For medications like valproate, monitoring liver function and platelet counts is critical. Additionally, a baseline pregnancy test is vital due to the medication’s teratogenic risk.

Why These Baseline Labs Are Essential for Bipolar Disorder

Lab work isn’t just a formality—it’s a critical step in ethical and safe prescribing practices. Unfortunately, some prescribers skip lab orders either because they fear interpreting abnormal results or simply don’t feel comfortable addressing them. Let’s not fall into these bad practices!

By fully understanding baseline lab tests and their implications, providers can confidently prescribe treatment plans while knowing when to refer patients to specialists for further evaluation.
