What is normal carboxyhemoglobin level?

Normal carboxyhemoglobin levels in healthy individuals are typically less than 1% in non-smokers and can be slightly higher (up to about 5-10%) in smokers due to exposure to tobacco smoke. Levels above these thresholds may indicate carbon monoxide exposure or poisoning. It is important to monitor carboxyhemoglobin levels in cases of suspected carbon monoxide exposure for appropriate medical intervention.
