recommended for best results in using venous blood. Use of anticoagulants
such as iodoacetate, or those containing fluoride is not advised
•
Very high (above 70%) and very low (below 20%) hematocrit can cause false
blood ketone test results. Talk to your healthcare professional to find out your
hematocrit level.
•
Vitamin C (ascorbic acid) when occurring in blood at normal concentration level
does not significantly affect results. Abnormally high levels of Vitamin C
(ascorbic acid) or other reducing substances will produce falsely high blood
ketone measurements.
•
N-acetylcysteine when in blood at normal concentration level does not
significantly affect results. N-acetylcysteine in the blood at abnormally high
levels will cause interference and produce falsely high blood
β
-Ketone
measurements. Do not use during or soon after N-acetylcysteine treatment.
•
Fatty substances such as Triglycerides up to 166.7 mmol/L (3,000 mg/dL) or
Cholesterol up to 27.8 mmol/L (500 mg/dL) have no major effect on blood
ketone test results.
