What is the CK-NAC assay used for?
What is CK-NAC?
The small amount of Creatine Kinase (CK) present in the blood primarily comes from skeletal muscle. CK is also found in striated muscle, brain and heart tissues. The CK concentration levels in the blood increase as a result of damage to bodily muscle or interferences with the muscle energy production such as myositis, which is inflammation of the muscles.
What is the CK-NAC assay used for?
The Randox CK-NAC reagent is used for the measurement of CK in serum or plasma to assess the extent of muscle damage and to monitor treatment.
The determination of CK-NAC activity in plasma or serum provides a sensitive marker for the detection of skeletal muscle disease; and is also useful to assess the extent of severe muscle trauma, crush injuries, burns or electrocution, and the likelihood of developing rhabdomyolysis. For more information on the spectrum of rhabdomyolysis, please click here [external link].
The determination of CK using creatine phosphate and adenosine‑5’‑diphosphate (ADP) as substrates rather than creatine and adenosine‑5’‑triphosphate (ATP) has several advantages in test performance as it allows for a faster reaction rate resulting in greater sensitivity. Small sample volumes are used and sample blanks are not required.
The UV method used is an optimised standard method according to the recommendations of the Deutsche Gesellschaft für Klinische Chemie.

What is the CK-MB assay used for?
What is CK-MB?
Creatine Kinase (CK) is internationally accepted as a sensitive and specific indicator of acute myocardial infarction (AMI). There are 3 major forms of the iso-enzymes of CK, CK-MM, CK-MB and CK-BB. CK-BB is produced by the brain in very small insignificant amounts. CK-MM is produced by the skeletal and heart tissue. CK-MB is produced by the heart muscle and increases when the heart muscle is damaged. For more information on the structure and function of CK isoenzymes in tissue, please click here.
What is the CK-MB assay used for?
CK-MB is a more sensitive marker to myocardial infarction than total CK activity as CK-MB has a lower basal level and a narrower normal range. In the vast majority of cases the CK-MB activity rises within 4 to 6 hours of an acute infarction. Between 10 to 24 hours, maximum values are observed. The CK-MB activity generally returns to normal between the third and fourth day post- infarction.
The Randox CK-MB reagent can measure small, but significant changes in CK-MB activity during the early hours following the onset of chest pain.

Wide Measuring Range – The Randox Ranbut assay has a measuring range of 0.100 – 5.75mmol/l for the comfortable detection of clinically important results.
Calibrator and controls available – Randox offer a complete testing package.
Applications available – Detail of instrument-specific settings for the convenient use of the Randox Ranbut assay on a variety of clinical chemistry analysers.
Traditional Methods
Ketogenesis is a biochemical process whereby the body produces ketone bodies (acetone, acetoacetate, beta-hydroxybutyrate). As ketone bodies are water soluble, they do not require lipoproteins for transport 1.
In healthy humans, small amounts of ketones are continuously made for the body to use an energy source. Ketone bodies increase in times of fasting and sleeping 1.
Physiological Significance
Urinalysis is an essential part of the diagnostic review for kidney disease and other renal impairments. Whilst the dipstick test allows for rapid and simultaneous chemical analyses of urine, including ketones, the chemical reactions on dipsticks are complicated and can be affected by oxidising, reducing, and discolouring substances in urine. Therefore, false positives and false negative results are common in dipstick testing 4.
Clinical Significance
When the carbohydrate stores are significantly decreased, or the fatty acid concentration is increased, there is an upregulation of the ketogenic pathway and consequently, an increased production of ketone bodies. This is commonly observed in alcoholism, type I diabetes and starvation. Most organs, including the brain, can utilise ketones whereas the heart utilises fatty acids as its source of energy, but can also use ketones. The liver however, cannot utilise ketones, despite producing them as the liver lacks the necessary enzyme ketoacyl-CoA transferase 1.
Ketosis is the presence of ketones. Whilst ketosis is not dangerous, if left untreated, especially in diabetes, ketoacidosis (high levels of ketones) develops 2.
In type 1 diabetes mellitus (T1DM), the body is unable to produce insulin resulting in bodily cells not receiving energy from glucose, causing the body to release hormones to breakdown fat for energy, producing ketones. If left untreated, diabetic ketoacidosis develops, a serious health condition. Diabetic ketoacidosis is commonly triggered by an illness, infection or missing insulin treatments 3.

What is the Cholinesterase (Butyryl) (BCHE / BuCHE) assay used for?
What is cholinesterase (butyryl)?
Cholinesterase (butyryl) (BCHE / BuCHE), also known as pseudocholinesterase, is a protein coding gene and is a serine hydrolase synthesised in the liver and is responsible for catalysing the hydrolysis of numerous choline esters. It can be found in the liver, intestinal mucosa, plasma, pancreas and the white matter of the central nervous system of mammals.
The Randox Cholinesterase (butyryl) reagent is used for the quantitative in vitro determination of BCHE in serum and plasma. BCHE can be used to diagnose cholinesterase (butyryl) deficiency and curariform drugs toxicity.
The Randox Cholinesterase (butyryl) reagent can also be used as a diagnostic and therapeutic marker for Alzheimer’s disease as BCHE activity progressively increases in patients with Alzheimer’s disease whereas acetylcholinesterase activity remains the same or declines. In Alzheimer’s disease, BCHE is found in association with beta-amyloid plaques and the cerebral cortex, whereas it is not commonly found in any other case. A study carried out by NCBI found that when the BCHE gene is not found in the brain, there are up to 70% less beta-amyloid plaques.

When measuring LDL cholesterol (LDL-C), it is the cholesterol mass within the LDL particles that is being measured. The LDL particle population within LDL is heterogeneous – meaning that the size, density & composition of each particle will be different. sdLDL-C is a subfraction of low density lipoprotein (LDL) with smaller particle size and higher density than larger more buoyant LDL. They all transport triglycerides and cholesterol to the tissues, but their atherogenesis varies according to their size. sdLDL-C will more readily permeate the inner arterial wall. sdLDL-C is more susceptible to oxidation and has a lower affinity to the hepatic LDL receptor, and as such circulates in the blood longer1.
As sdLDL-C is particularly atherogenic, a person with elevated sdLDL-C levels has a 3-fold increased risk of myocardial infarction (MI)2.
sdLDL-C measurement therefore provides a more comprehensive understanding of cardiovascular disease (CVD) risk compared to traditional LDL-C tests.
Reducing sdLDL-C levels will aid in reducing the risk of CVD and MI. High dose statin therapy has been proven to aid in reducing the levels of sdLDL-C as a risk factor for cardiovascular events and high risk patients. Elevated levels of sdLDL-C arise from multiple sources. A major factor is a sedentary lifestyle with a diet high in saturated fat. Insulin resistance and pre-diabetes have also been implicated, in addition to genetic predisposition3.
The measurement of LDL-C or the review of levels within arteriosclerotic coronary heart disease (ASCHD) treatment are known within different guidelines (including ATP III, AHA/ ACC, ESC/ EAS and NICE). However doubt remains on the impact of targeting LDL-C only. The inclusion of sdLDL-C within the clinical testing panel will assist in removing this doubt.
The only direct automated sdLDL-C kit on the market, the Randox sdLDL-C test is a direct method for the quantitative determination of sdLDL-C using automated chemistry analysers capable of accommodating two-reagent assays. The assay consists of two steps and is based on the use of well-characterised surfactants and enzymes that selectively react with certain groups of lipoproteins.
