Toxicology Screen
Urinalysis (UA)
Basic Laboratory Interpretation: Complete Blood Count - Answers --measures RBCs,
WBCs, hemoglobin, hematocrit, and platelets
-includes a differential of the WBCs
-In mental health, the CBC is used to rule out medical conditions that may present with
symptoms that can be attributed to both medical and psychiatric diagnoses
• Ex: rule out anemia as a cause for depressive symptoms and fatigue
• Ex: rule out infection as a cause of acute mental status changes
RBCs: 4.5-6.0 million/microliter
Hemoglobin: 12-18 grams/100 mL

Basic Laboratory Interpretation: Comprehensive Metabolic Panel (CMP) - Answers -
common blood test used to determine general health status
-fluid and electrolyte balance, status of the body's metabolism, liver function, and kidney
function
-used to monitor the effects of medications, such as antipsychotics, on liver function and
glucose levels
-rule out medical conditions that could cause symptoms
• Ex: changes in mood or cognition
Sodium (Na+): 136-145 mEq/L
Postassium (K+): 3.5-5.0 mEq/L
Chloride (Cl-): 95-105 mEq/L
Bicarbonate (HCO3-): 22-28 mEq/L
Calcium, serum (Ca 2+) 8.4-10.2 mg/dl
Glucose, serum Fasting: 70-110 mg/dl; 2-h postprandial: <120mg/dl
Cholesterol, serum: REC<200 mg/dl
Total Protein 6.0-7.8 g/dl
Albumin 3.5-5.5 g/dl
-Kidney Tests
• Creatinine, serum 0.6-1.2mg/dl
• Urea nitrogen, serum (BUN) 7-18mg/dl
-Liver Tests
• Alanine aminotransferase (ALT), serum: 8-20 U/L
• Aspartate aminotransferase (AST), serum: 8-20 U/L
• Bilirubin, serum (adult) Total//Direct: 0.1-1.0 mg/dl // 0.0-0.3 mg/dl
• Phosphatase (alkaline), serum: 20-70 U/L
Basic Laboratory Interpretation: Thyroid Function Tests (TFTs) - Answers -used to rule
out thyroid disorders as a cause for symptoms
• symptoms related to thyroid disorders include anxiety, restlessness, depression, mood
swings, sleeping difficulties, difficulties with concentration, short-term memory lapses,
and lack of mental alertness

B12 can affect mood and other brain functions

-high prevalence of vitamin D deficiency in clients with psychiatric disorders such as
schizophrenia, depression, seasonal affective disorder, and cognitive impairment
-Symptoms of vitamin D deficiency include depression, irritability, anxiety, psychosis,
