Beta-hydroxybutyrate (Ketone)      Alcohol, Ethyl              Calculated Osmolality
Interpretation                        Metabolic Panel          Osmolality                    
Osmolality Gap                     pH Venous

Comment: Complete and send to Lab a Toxic Volatile Screen Patient Information Sheet.
Specimen: 

1 lithium Heparin PST tube, 1 plain red top, 1 gray top, and 1 small green top tube completely filled and on ice. Use aqueous betadyne for cleaning venipuncture site, not alcohol swab.

Processing:

1.0 ml heparin plasma from a PST tube for metabolic panel and osmolality. Perform alcohol testing upon first opening. Keep small green top tube closed and on ice for venous pH. Plain red top tube and gray top tube are used only if confirmatory tests are indicated.

Reference value:

Refer to individual test entry and Toxic Volatile Screen Laboratory Results for Frequent Situations table which follows on next page. Mercy technical staff, refer to Osmolality procedure for analysis, calculations,& interpretation.         

Performed:  On receipt.  Available stat.
Method:  Refer to individual test entry.

  1. Only one point of time in the normal disposition of each of these ingredients is represented by these results.
  2. A trace of ketones may be observed in individuals who have not eaten for many hours.
  3. Acetest is specific for the detection of acetoacetic acid and acetone.  It is about 10 times more sensitive to acetoacetic acid than acetone and will not react with betahydroxybutyric acid.  Acetest is NOT available at MMC-NI.  The only Ketone test available at MMC-NI is Beta-hydroxybutyrate which will not pick up acetone or acetoacetic acid.
  4. Ethylene glycol is metabolized to oxalate; oxalate crystals may be found in the urine.
  5. Clinical history, ketones positive, and elevated glucose will identify this group.
  6. Alcoholic ketoacidosis usually occurs 1-2 days after binge drinking.  Ethanol has disappeared from the blood.  The ketone test is elevated because B-hydroxybutyrate is the most abundant ketone in this setting.
