Biomarker
hs-CRP and inflammation
Inflammation markers can add context for fatigue, mood, metabolic risk, and medical complexity. They do not diagnose depression.
Review frame
How hs-CRP and inflammation enters the review
Inputs
- Recent lab value with reference range
- Related symptoms
- Medication and supplement list
- Sleep pattern
- Relevant medical history
- What changed over time
Output
- Symptom and timeline summary
- Lab-pattern read in psychiatric context
- Medication, supplement, sleep, and substance review
- Psychiatric-medical differential
- Named pathway for care or monitoring
Not this
- Not emergency care
- Not a diagnosis from labs
- Not a medication or supplement change by website
- Not a replacement for primary care, psychiatry, or therapy
- Not proof that biology explains every symptom
Clinical read
hs-CRP and inflammation can change the differential. It cannot carry the case by itself.
What the marker can show
hs-CRP is a nonspecific inflammatory signal. It can rise from infection, injury, autoimmune disease, obesity, smoking, dental disease, or cardiometabolic risk.
Where symptoms can blur
Fatigue, low mood, pain, sleep disruption, or reduced exercise tolerance Metabolic risk, inflammatory disease history, or recent infection Symptoms that fluctuate with illness, stress load, or inflammatory flares
What it does not prove
This marker does not diagnose depression, anxiety, ADHD, insomnia, or burnout by itself.
When it matters more
Symptoms, timing, and risk decide how much weight this marker gets.
- Fatigue, low mood, pain, sleep disruption, or reduced exercise tolerance
- Metabolic risk, inflammatory disease history, or recent infection
- Symptoms that fluctuate with illness, stress load, or inflammatory flares
Clinical discussion
What to discuss with a clinician.
- Whether hs-CRP should be repeated when acute illness has passed
- Cardiometabolic and inflammatory context with primary care
- Why inflammation is a contributor hypothesis, not proof of psychiatric causation
Common questions
Questions people ask before they start.
Can this marker diagnose the problem?
No. This marker can change what belongs in the differential. A responsible review still requires clinical history, symptoms, timing, medication context, risk review, and the appropriate clinician relationship.
What does the review actually give me?
A written psychiatric-medical synthesis: what appears more likely, what remains possible, what seems less likely, what needs another clinician, and what should be monitored or left alone.
Is this emergency care?
No. If symptoms are acute, dangerous, rapidly worsening, or involve possible self-harm, psychosis, mania, delirium, withdrawal, chest pain, neurologic symptoms, or medical instability, use emergency or urgent care.
