Carbon Monoxide Poisoning Testing Overview

In order to gauge your current state of health, our clinic will often request copies of your last two years of medical testing and will often recommend further testing as needed.  Our clinic does request some testing that is and not commonly performed in more "mainstream" medical clinics.  24-hour heavy metal testing with provoking agent, neurotransmitter analysis, food sensitivity testing, comprehensive stool testing and Candida antigen testing are commonly recommended by our medical staff.   Some of these are discussed in detail in the links in this section.

What to Expect on Your First Visit:

First office visits typically last 45-60 minutes.  Your doctor will review your intake form with you and gather a detailed medical history.  A partial physical exam is usually performed and medical records are often requested from your primary care physician and/or other doctors.  Specialty laboratory testing may be recommended.  Most clients are offered an initial protocol consisting of nutritional supplementation, dietary and life style recommendations.

First Visit: Blood Test

To assess and identify kidney, liver, blood sugar and other key factors such as blood cholesterols. The results are explained to the patient, giving him/her a fuller understanding of the blood chemistry, so that they may take control.

Patients are required to fast for 14 hours before the test. Water may be drunk freely, but not tea, coffee, juices or other beverages. Appointments are normally arranged for mid-morning so that food and drink can be consumed up to 8pm the previous evening. On the day of the appointment, any prescribed medication should be taken with water as normal.

Patients are recommended to bring food to eat after the blood sample has been taken. Diabetics should advise the clinic, and separate arrangements will be made.

First Visit: Urine Analysis

To establish exactly how the kidneys are functioning. Patients are required to collect urine over a period of 24 hours. This should be as near the date of the blood test as possible, but must not include the 14 hours fasting period prior to the appointment.

A recommended timetable is that the first urine of the day should be excluded, than all subsequent urine for the next 24 hours collected in clean plastic containers. (If collection starts at 8am, this process must be followed until 8am the following day.) Eg. Appointment 10am Friday, fasting commences Thursday 8pm. Urine collection starts Wednesday 8am. until Thursday 8am.

Containers should be clearly labeled with the patient's names and brought to the clinic at the time of their appointment.

First Visit: Resting ECG for Doctors Report

The electrocardiograph (ECG) determines the condition of the heart and measures its actions and the pulse.

The doctor in charge reports any findings in his medical notes.

Specific Carbon Monoxide Poisoning Testing:

Carbon monoxide (CO) is a colorless, tasteless, odorless, and non-irritating gas formed when carbon in fuel is not burned completely. It enters the bloodstream through the lungs and attaches to hemoglobin (Hb), the body's oxygen carrier, forming carboxyhemoglobin (COHb) and thereby reducing oxygen (O2) delivery to the body's organs and tissues.

High COHb concentrations are poisonous. Central nervous system (CNS) effects in individuals suffering acute CO poisoning cover a wide range, depending on severity of exposure: headache, dizziness, weakness, nausea, vomiting, disorientation, confusion, collapse, and coma.

What is the Carboxyhemoglobin Test?

The Carboxyhemoglobin test is a blood test used to detect carbon monoxide poisoning.

Indications and Contraindications

The Carboxyhemoglobin test is needed if you have been:

  • Exposed to sources of carbon monoxide such as tobacco smoke, exhaust fumes, fires, petroleum gas, unvented gas heaters
  • Experiencing nausea and vomiting, headache, dizziness, confusion

How do you prepare for the Carboxyhemoglobin Testing?

Testing for carbon monoxide poisoning must be done as soon as possible. There is no preparation required such as fasting or sedation. However, if you are a smoker, do not smoke before the test and inform your physician about your smoking habits. Talk to your physician of any concerns you have regarding the test.

How does it feel? How long will it take?

The blood sample is taken from a vein in your arm. An elastic band is wrapped around your upper arm. It may feel tight. You may feel nothing at all from the needle while your blood is being drawn, or you may feel a quick sting or pinch depending on your sensitivity to pain. Drawing of 5 to 10 ml venous blood usually last for a few minutes.

Expected effects after the test:

Normally, there are no major effects after the test. Commonly, patients may feel a little sore and slight bleeding may occur on the needle site. Bruising or swelling may occur. 

Special instructions after the test:

If advised by the health care professional, apply pressure on the area. Bandage may then be removed 30 minutes after the test.  Avoid doing strenuous activities to avoid swelling, pain, or bleeding of the needle site.

Interpretation of Results:

Normal Findings:

      • Non-smokers: less than 3% saturation of total hemoglobin bonded to carbon monoxide
      • Light smokers: 2%-5%
      • Heavy smokers: 5%- 10%
      • Newborn: greater than or equal to 12%

Critical Value:greater than or equal to 20%

High carbon monoxide content in the blood indicates carbon monoxide poisoning. Values that are below 10% have lower risk of carbon monoxide poisoning.


People who have been exposed to carbon monoxide should be tested for poisoning immediately. The carboxyhemoglobin test may also be used to determine possible poisoning due to complaints of headache, dizziness, nausea, vomiting vertigo and vomiting. Hemoglobin saturated with more than 60% of carbon monoxide will result to death.

The Right Diagnosis and Treatment for Carbon Monoxide Poisoning

Once the comprehensive review is completed for each patient, our doctors and our team of medical professionals will evaluate your diagnosis. At this point, our doctors will spend one on one time with you to interpret and explain your results. Together you will explore your goals and discuss your treatment plan options. These treatment plans can be implemented using multiple modalities such as medications, hormones, diet, supplements, behavior and lifestyle changes, and alternative therapies. Our doctors will prescribe a preventative and comprehensive treatment plan that is tailored to your needs and fits into your lifestyle.
