に関する。Detailed Description of the Invention (Field of Industrial Application) The present invention maintains the initial blood sugar level by rapidly inhibiting the drop in blood sugar due to glycolysis in the blood, and can be used as a sample for blood sugar testing. This invention relates to blood collection tubes that allow biochemical tests to be performed on the same specimen at the same time.

ものがある。(Prior Art) Surface fluid components are measured for various clinical tests and pathological research. The blood collection tube used to measure these blood components consists of a blood collection tube body made of glass or synthetic resin, and a stopper made of rubber or synthetic resin used at the mouth of the blood collection tube body. Some of these blood collection tubes have a glycolytic inhibitor, anticoagulant, or other drug stored in the bottom of the tube in the form of powder, granules, or aqueous solution, depending on the purpose of the test.

検体にいたっては、更に長時間保存されろことがある。Generally, when testing blood components, a certain amount of time is required from blood collection to measurement. In particular, in large hospitals and testing centers, where large numbers of specimens are handled, it is unavoidable that blood samples are stored at room temperature for at least several hours due to the flow of testing operations, and in some cases, blood samples are collected and delivered. Samples may need to be stored for even longer periods of time.

これらの公知の解糖阻止剤には以下のような問題点があ
った。In the case of blood sugar testing, blood sugar levels tend to drop due to glycolysis during the storage period after blood collection, so blood collection tubes containing a glycolytic inhibitor are used to suppress this. Conventionally, fluoride salts, monohalogenated acetic acid metal salts, citric acid, D-mannose, and the like are known as glycolytic inhibitors. but,
These known glycolytic inhibitors have the following problems.

いという問題点があった。Fluoride salts and monohalogenated acetic acid metal salts have a glycolytic blocking effect by inhibiting the actions of enolase and glyceraldehyde-3-phosphate dehydrogenase, respectively, but these enzymes inhibit lower-level glycolysis. Since it is an enzyme, it takes time for the inhibitory effect to appear, and during that time blood sugar levels drop slightly, so there is a problem that it is not fast-acting. However, once the inhibitory effect occurs, blood sugar levels are maintained continuously thereafter. Furthermore, these glycolytic inhibitors tend to cause hemolysis in blood samples, and when hemolysis occurs, hemoglobin and potassium leak from red blood cells into plasma. Therefore, in this case,
These items cannot be measured accurately. Furthermore, it also introduces errors in blood glucose measurement methods that use colorimetric methods. Furthermore, these glycolytic inhibitors are not selective inhibitors of glycolytic enzymes in red blood cells, but inhibit enzymes in general, and therefore enzyme components in blood samples cannot be measured. In other words, the use of these glycolytic inhibitors allows for tests such as blood sugar tests, electrolytes such as potassium and sodium, and various enzyme tests.
There was a problem in that so-called biochemical tests could not be performed simultaneously using the same specimen.
クエン酸は、ホスホフルクトキナーゼという解糖系の上

なり、赤血球が変性し溶血が激しくおこる。溶血すると
、61述の7フ化塩やモノハロゲン化酢酸金属塩と同様
に、血糖と生化学検査を同一検体で同時に測定し得ない
。Citric acid inhibits phosphofructokinase, an enzyme at the upper level of glycolysis, and therefore exhibits a rapid glycolysis inhibiting effect. However, citric acid is strongly acidic (pH 1-2), so
When mixed with blood, the pH of the blood becomes acidic (pH 4 to 5), red blood cells are denatured, and hemolysis occurs violently. When hemolyzed, blood sugar and biochemical tests cannot be performed simultaneously on the same specimen, similar to the heptafluoride salt and monohalogenated metal acetate described in 61.
D−マンノースは、グルコースと同様にヘキソキナーゼ

応は、同時に行なえる。しかし、血糖測定法のうちで、
最近多く使用されているグルコース脱水素酵素を用いる
方法では、基質特異性の低い酵素が使われている場合、
グルコースだけでなく、異性体のD−マンノースも脱水
素される。Like glucose, D-mannose is a substrate for hexokinase, and thus competes with glucose in the glycolytic action of hexokinase on glucose. This prevents glycolysis and is therefore fast-acting. Furthermore, since hemolysis does not occur, blood sugar and biochemical tests can be performed simultaneously on the same specimen. However, among blood sugar measurement methods,
In the method using glucose dehydrogenase, which has been widely used recently, if an enzyme with low substrate specificity is used,
