An overabundance of ketones in the
blood (ketonemia) leads to a process
called ketoacidosis which leads to a
drop in the pH of the blood. This can
be indicated by fatigue, extreme cold,
confusion, and in severe cases, loss of
consciousness and eventually death.
Long term ketosis at less significant
levels can lead to organ damage.
Ketones are also excreted when you
exhale, which is why you will
sometimes notice a fruity or acetonelike smell on the breath of a person
who is entering starvation.
When testing at home, it is best to use
fresh urine as urine continues to break
down after it is excreted and this can
affect results. Strips should not be kept
in the bathroom, but in a dry place at
room temperature. Humidity and other
moisture can also affect efficiency. High
levels of salicylates (salicylic acid) can
also interfere with ketone
measurement. Salicylates are found in
aspirin, some dandruff shampoos,
some acne washes, and some foods.
The compound is also found under ripe
produce, almonds, peanuts, water
chestnuts, and some spices. If any of
these are safe foods that make up a
large part of your diet, let your doctor
know so it can be considered when the
lab results are interpreted.

When monitoring your levels at
home, pay careful attention to your
doctor’s instructions. Trace or even
small ketones can be normal, and may
come and go, while higher levels
should always be discussed with your
care provider. Rapid fluctuations can
be important as well.
