CRP, Standard
What This Test Measures
Standard CRP for detecting inflammation; less sensitive than hs-CRP; appropriate for acute infection monitoring.
Preparation
TIMING: Avoid testing within 48–72 hours of intense exercise, acute illness, injury, or infection — all dramatically spike CRP. Retest in 2–3 weeks if you get an unexpectedly high result. The functional medicine community views even mildly elevated CRP (above 1.0 mg/L) as evidence of systemic inflammation worth investigating. Always consider alongside other inflammatory markers (ESR, ferritin) for the full picture. These notes reflect common practices in functional medicine communities.
