Disposable test strips and a wet chemistry method for measuring each of beta-hydroxybutyrate alone, combined beta-hydroxybutyrate and acetoacetate or total ketone bodies (i.e., beta-hydroxybutyrate, acetoacetate and acetone) in human bodily fluid samples, including but not limited to urine, saliva or sweat are described. The test strips need only be dipped in the sample and can be used by anyone in almost any milieu. Measurement can be made electrochemically, spectrophotometrically, fluorometrically or by comparision to a color standard. Combined acetoacetate and beta-hydroxybutyrate which account for 97-98% of total ketone bodies and may be measured in a cyclic reaction that occurs at pH about 7.0 to about 8.3 with beta-hydroxybutyrate dehydrogenase, (beta-HBD), nicotinamide adenine dinucleotide, a tetrazolium dye precursor and an electron mediator. Using this reaction, false positive results obtained from urine samples taken from patients on sulfhydryl drugs are avoided. beta-HBD from some sources was found to cause false negative results in samples (e.g. urine) containing high chloride content due to chloride inhibition of beta-HBD. Using a simple test for chloride inhibition, it was found that beta-HBD from Alcaligenes is not so inhibited. Using either beta-HBD that is not inhibited by chloride or using 10-20 times the normal concentration of this enzyme eliminates false negatives in samples having substantial chloride content, such as urine, both in the reaction described above and in other reactions disclosed for measuring each of beta-hydroxybutyrate alone, combined beta-hydroxybutyrate and acetoacetate and total ketone bodies, all of which reactions occur in the pH range of about 8.6 to about 9.5.

In the production of hydrogen peroxide, a higher alcohol component in an organic solvent changes into a ketone body and increase in the ketone bodies reduces water content of a working solution and causes deterioration of catalytic activity. In addition, increase in the ketone bodies may obstruct stable and safe operation during the production of hydrogen peroxide due to decrease in the solubility of anthrahydroquinones, crystallization, precipitation, etc. The objective of the present invention is to provide a method for improving hydrogen peroxide production efficiency by regenerating an altered substance (ketone body) derived from a polar solvent in the working solution used for the production of hydrogen peroxide by the anthraquinone method to the original alcohol component. Hydrogen peroxide can be produced more efficiently by distilling off the organic solvent component including the ketone body from the working solution which has been used over time and hydrogenating the same under the presence of a metal catalyst to regenerate to the original alcohol component.

The disclosed testing method for measuring the severity of an illness in real-time can assess the severity of an illness in more detail than the existing APACHE II and SOFA scores. Said method can accurately measure the amount of ATP in a sample and accurately and quickly deduce the "state of intracellular energy, which organisms need in order to live" from the amount of ATP, and thus can evaluate the severity of an illness. Furthermore, the ATP concentration is used as an index to re-evaluate the amount of lactic acid accumulated in the sample as a result of breakdowns in metabolic balance accompanying increasing disease severity (specifically, the lactic acid level (mM) is divided by the ATP concentration (mM)), thereby providing a novel biomarker, the ATP-Lactate Energy Risk Score (A-LES), that can assess the severity of an illness. Additionally, the ATP concentration is used as an index to re-evaluate the ketone body level in the sample (specifically, the ketone body level (mM) is divided by the ATP concentration (mM)), thereby providing a novel biomarker, the ATP-Ketone Energy Risk Score (A-KES), that can assess the severity of an illness.
