The tube for CPK (creatine phosphokinase) isoenzymes is typically red or gold, depending on the laboratory.
Creatine phosphokinase (CPK) is typically collected in a red-top tube for serum or a green-top tube for plasma.
A lavender or purple top tube is typically used to collect a CPK (Creatine Phosphokinase) blood test.
The CPK color convention for test tubes typically assigns carbon with the color black, oxygen with red, and nitrogen with blue.
The Labcorp tube color for creatine phosphokinase (CPK) is typically red or gold, depending on the specific type of test being conducted. It is best to confirm with the laboratory or consult the test requisition form for the exact tube color required.
The color tube commonly used for CPK (creatine phosphokinase) is red or gold, which indicates a serum separator tube (SST) that contains a clot activator and gel separator to separate serum from cells after centrifugation.

Isoenzymes in blood serum can be used to diagnose disease.
CPK (Corey-Pauling-Koltun) coloring refers to a specific color scheme used to represent atoms in molecules, where carbon is typically shown in black, oxygen in red, nitrogen in blue, and other elements in various colors like white, green, or pink. A CPK color code is often used with molecular models or in scientific illustrations to visually represent different atoms within a molecule.

Cpk = Cp (Process Capability) + p (katayori) Japanese for deviation. Cpk = Deviation of process capability
DefinitionThe CPK isoenzymes test measures the different forms of creatine phosphokinase (CPK) in the blood. CPK is an enzyme found mainly in the heart, brain, and skeletal muscle.See also: Creatine phosphokinase testAlternative NamesCreatine phosphokinase - isoenzymes; Creatine kinase - isoenzymes; CK - isoenzymesHow the test is performedBlood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.If you are in the hospital, this test may be repeated over 2 or 3 days. A significant rise or fall in the total CPK or CPK isoenzymes can help your health care provider diagnosis certain conditions.How to prepare for the testUsually, no special preparation is necessary.Tell your doctor about all the medications you are taking. Certain medications can interfere with test results. Drugs that can increase CPK measurements include the following:Amphotericin BAmpicillinSome anestheticsAnticoagulantsAspirinClofibrateDexamethasoneFurosemideMorphineAlcoholCocaineHow the test will feelWhen the needle is inserted to draw blood, you may feel moderate pain, or only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedThis test is done if a CPK test reveals that your total CPK level is elevated. CPK isoenzyme testing can help pinpoint the exact soure of the damaged tissue.CPK is made of three slightly different substances:CPK-1 (also called CPK-BB) is found mostly in the brain and lungsCPK-2 (also called CPK-MB) is found mostly in the heartCPK-3 (also called CPK-MM) is found mostly in skeletal muscleWhat abnormal results meanHigher-than-normal CPK-1 levels:Because CPK-1 is found mostly in the brain and lungs, injury to either of these areas can increase CPK-1 levels. Increased CPK-1 levels may be due to:Brain cancerBrain injury(due to injury, stroke, or bleeding in the brain)Electroconvulsive therapyPulmonary infarctionSeizureHigher-than-normal CPK-2 levels:CPK-2 levels rise 3 - 6 hours after a heart attack. If there is no further heart muscle damage, the level peaks at 12 - 24 hours and returns to normal 12 - 48 hours after tissue death.Increased CPK-2 levels may also be due to:Electrical injuriesHeart defibrillation (purposeful shocking of the heart by medical personnel)Heart injury (for instance, from a car accident)Inflammation of the heart muscle usually due to a virus (myocarditis)Open heart surgeryCPK-2 levels do NOT usually rise with chest pain caused by angina, pulmonary embolism (blood clot in the lung), or congestive heart failure.Higher-than-normal CPK-3 levels are usually a sign of muscle injury or muscle stress and may be due to:Crush injuriesMuscle damage due to drugs or being immobile for a long time (rhabdomyolysis)Muscular dystrophyMyositis(skeletal muscle inflammation)Receiving many intramuscular injectionsRecent nerve and muscle function testing (electromyography)Recent seizuresRecent surgeryStrenuous exerciseSpecial considerationsFactors that can affect test results include cardiac catheterization, intramuscular injections, recent surgery, and vigorous and prolonged exercise or immobilization.Isoenzyme testing for specific conditions is about 90% accurate.ReferencesAnderson JL.

Cytochrome P-450 isoenzymes are a group of enzymes in the liver that are involved in drug metabolism. Some examples of cytochrome P-450 isoenzymes include CYP3A4, CYP2D6, and CYP1A2. These isoenzymes play a crucial role in the breakdown and elimination of a wide range of drugs and toxins from the body.
The color of the tube for electrolyte testing is typically green.
