Molecular Controls for Respiratory Infection Testing

Respiratory Infections

Flu is a contagious respiratory illness cause by influenza viruses that infect the throat, nose, and sometimes lungs. It can cause illness and sometimes death. Getting vaccinated is the best way to prevent catching flu [1].

There are four types of seasonal flu, A, B, C, and D. Types A and B cause seasonal epidemics of disease. Illnesses range from severe to mild and can even result in death in high risk groups. High risk groups include, pregnant women, children under 5 years of age, the elderly, and people with chronic or immunosuppressive medical conditions [2].

Flu season begins as early as October, reaches its peak in February, and ends in March. In the southern hemisphere, flu season falls between June and September. Wherever it’s cold, it’s flu season.

Diagnosing Flu

A test to detect Influenza viruses can be used to determine whether a patient has the flu. A swab is taken from either the nose or back of the throat and sent for testing. Molecular assays can be used to detect genetic material of the virus [3]. Molecular methods play an important role in the diagnosis and surveillance of influenza viruses. Molecular diagnostics allow timely and accurate detection of influenza and are already implemented in many laboratories. The combination of automated purification of nucleic acids with real-time PCR should enable even more rapid identification of viral pathogens such as influenza viruses in clinical material [4].

Cardiac Quality Control Solutions

For this month’s product spotlight, we have chosen our whole range of cardiac quality control solutions. Randox offers options for both Internal Quality Control (IQC) and External Quality Assessment (EQA).

29th September is World Heart Day. World Heart Day is a global campaign during which individuals, families, communities and governments around the world participate in activities to take charge of their heart health and that of others.

Cardiovascular disease (CVD) is a term to describe conditions that affect the heart and blood vessels. It is normally associated with a build up of fatty deposits in the arteries and an increased risk of blood clots. CVD is the leading casues of death globally, representing around 30% of all deaths. A healthy lifestyle can help prevent CVD; however, increasingly busy lifestyles mean that it is difficult to avoid CVD. This means it is vitally important that individuals are tested for CVD and to ensure that diagnoses are acurate.

Acusera Internal Quality Controls

The accurate diagnosis of a potentially life threatening cardiac event is essential in order to avoid misdiagnosis and/or incorrect treatment. The Acusera Cardiac Quality Controls have been designed to cover a wide range of cardiac markers at clinical decision levels eliminating the need for additional low level controls at extra expense. Available in a choice of both liquid ready-to-use and lyophilised formats, they are ideal for use at the point-of-care and in the laboratory.

Clinical Significance

The clinical significance of some selected analytes.

  • Androstenedione

    Androstenedione is an androgen, which are hormones responsible for the induction of sexual differentiation and produce secondary male physical characteristics such as a deep voice and facial hair. Another example is testosterone. They are also present in females as precursors to female hormones (such as estrogen).

    This test measures the amount of androstenedione in the blood. Because AD has its origins in the adrenal glands, it is useful as a marker of adrenal gland function, of the function of the ovaries or testicles, and androgen production.

    An androstenedione level may be used to [1]:

    Evaluate adrenal gland function and distinguish between androgen-secreting conditions that are caused by the adrenal glands from those that originate in the ovaries or testicles, if results of DHEAS and testosterone testing are abnormal
    Help diagnose tumours in the outer layer (cortex) of the adrenal gland or tumours outside of the adrenal gland that secrete ACTH (ectopic) and separate these conditions from ovarian or testicular tumours and cancers
    Diagnose congenital adrenal hyperplasia (CAH) and monitor CAH treatment, in addition to tests for testosterone and 17-hydroxyprogesterone
    Help diagnose polycystic ovarian syndrome (PCOS) and help rule out other causes of infertility, no monthly menstrual periods (amenorrhea), and excess body and facial hair (hirsutism) in women who have abnormal results on tests for DHEAS, testosterone, and other hormones such as FSH, LH, prolactin, and estrogen
    Help determine the cause of delayed puberty and investigate suspected ovarian or testicular failure
    Investigate and diagnose the cause of male physical characteristics (virilisation) in young girls and early (precocious) puberty in young boys
  • Digoxin

    Digoxin is a therapeutic drug used to treat abnormal heart rhythms and failure. Heart failure causes the heart to become less effective at circulating blood, resulting in blood backing up in the hands, legs, liver, and lungs, causing swelling.

    This test measures the level of digoxin in the blood. Digoxin is prescribed to patients to alleviate symptoms of heart failure by strengthening contractions, helping the heart pump blood more effectively. Digoxin can also be used to treat arrhythmias. It cannot be used to cure heart failure or arrhythmias but can help to manage the symptoms along with other medication, exercise and diet.

    Digoxin levels are monitored due to the drug’s narrow safety range. If the level is too high, toxicity may occur, if too low, symptoms may recur.

    A Digoxin level may be used to [2][3]:

    Monitor the concentration of the drug in the patient's blood
    Determine if a patient's symptoms are due to insufficient levels of Digoxin or due to digoxin toxicity
    Increase the strength and efficiency of heart contractions, helping control the rate and rhythm of the heart
    Slows electrical conduction between the atria and the ventricles, which is useful in treating abnormally rapid atrial rhythms that can cause heart attacks
  • Luteinizing Hormone (LH)

    Luteinizing Hormone (LH) is associated with the reproductive cycle and the release of an egg from the ovary in women and testosterone production in men. LH production is a complex system controlled by the hypothalamus in the brain, hormones produced in the testes and ovaries, and the pituitary gland.

    This test measures the amount of luteinizing hormone in the blood or urine. It is used alongside other tests such as FSH, estradiol, progesterone, and testosterone to investigate reproductive irregularities.

    A luteinizing hormone level may be used [4]:

    In both men and women:

    In the workup of infertility
    To aid in the diagnosis of pituitary disorders that can affect LH production
    To help diagnose conditions associated with dysfunction of the ovaries or testicles

    In women:

    In the investigation of menstrual irregularities
    To detect a surge in LH levels during the menstrual cycle, helping determine when a woman is likely to be the most fertile

    In children:

    To diagnose delayed and precocious (early) puberty. Irregular timing of puberty may be an indication of a more serious problem involving the hypothalamus, the pituitary gland, the ovaries or testicles, or other systems
  • Insulin

    Insulin is a hormone produced and stored in the beta cells of the pancreas. It is secreted as a response to an elevated glucose level following a meal and is vital in the transportation and storage of glucose, the body’s primary source of energy. Insulin regulates blood glucose by helping transport it from blood to cells.

    This test measures the amount of insulin in the blood. After a meal, carbohydrates are broken down into glucose, this is then absorbed into the blood causing the blood glucose level to rise, this then falls as it moves into cells. If an individual cannot produce enough insulin, or if they are insulin resistant (cells are resistant to insulin’s effects), glucose does not reach the body’s cells and they starve. The blood glucose level will rise to an unhealthy level, which can cause various complications, including Diabetes.

    An insulin level may be used to [5]:

    Diagnose an insulinoma, verify that removal of the tumor has been successful, and/or to monitor for recurrence
    Diagnose the cause of hypoglycemia in an individual with signs and symptoms
    Identify insulin resistance
    Monitor the amount of insulin produced by the beta cells in the pancreas (endogenous); in this case, a C-peptide test may also be done. Insulin and C-peptide are produced by the body at the same rate as part of the conversion of proinsulin to insulin in the pancreas
    Determine when a type 2 diabetic might need to start taking insulin to supplement oral medications
    Determine and monitor the success of an islet cell transplant intended to restore the ability to make insulin, by measuring the insulin-producing capacity of the transplant

    What test results mean [5]:

    Disorder
    Fasting Insulin Level
    Fasting Glucose Level
    Insulin resistanceHighNormal or somewhat elevated
    Not enough insulin produced in beta cells (diabetes, pancreatitis)LowHigh
    Hypoglycemia due to excess insulin (insulinomas, cushing syndrome)Normal or HighLow

  • Stable to expiry date at 2°C – 8°C
  • Reconstituted stability of up to 5 days at 2°C – 8°C and 4 weeks at -20°C
Clinical Significance
  • Procalcitonin

    Procalcitonin (PCT), a protein that consists of 116 amino acids, is the peptide precursor of calcitonin, a hormone that is synthesized by the parafollicular C cells of the thyroid and involved in calcium homeostasis.

    Procalcitonin is also produced by the neuroendocrine cells of the lung and intestine and is released as an acute-phase reactant in response to inflammatory stimuli, especially those of bacterial origin. This raised procalcitonin level during inflammation is associated with bacterial endotoxin and inflammatory cytokines.

    Procalcitonin (PCT) versus C-reactive protein (CRP)

    CRP is the most common laboratory marker used in the clinical setting to evaluate systemic inflammatory response to an infectious agent.

    Procalcitonin is a more useful diagnostic inflammation parameter than CRP in patients with pediatric neutropenic fever, both in estimating the severity of infection and the duration and origin of the fever. Procalcitonin is also a more reliable parameter in the diagnosis of bacterial sepsis, allowing better differentiation among sepsis-related fatalities.[2]

  • Calcitonin

    A calcitonin assay is helpful in identifying patients with nodular thyroid disease. It is often performed in the hope of identifying early MTC. Successful treatment of MTC depends on early detection; late detection confers a poor prognosis. In addition, calcitonin levels are reported to be increased in other malignancies, such as carcinoid tumors, lung carcinoma, melanoma, pancreatic and breast carcinoma, and pheochromocytoma.

    Calcitonin is produced and released by parafollicular cells of the thyroid. Calcitonin is derived from larger precursors. Precalcitonin is cleaved to procalcitonin, which is further cleaved to immature calcitonin and then to mature calcitonin, a monomer of a 3.5-kd peptide composed of 32 amino acids, which is the only biologically active form.

    Calcitonin’s precise physiologic role in humans remains to fully understood. It is known to act on the bones, kidneys, and gastrointestinal tract, binding directly to osteoclasts, thereby directly inhibiting osteoclastic bone resorption. Although this inhibition may be important in short-term control of calcium loads, it is short-lived and likely plays an insignificant role in overall calcium homeostasis. Calcitonin also inhibits the action of parathyroid hormone and vitamin D. [1]

  • Gastrin

    Gastrin testing is employed in the diagnosis of gastrinoma, either with or without Zollinger-Ellison syndrome, and in the investigation of pernicious anemia and achlorhydria.

    In patients who have undergone antrectomy with vagotomy, gastrin levels are reduced. In contrast, gastrin levels are increased in Zollinger-Ellison syndrome.[3]

  • Renin

    Renin, also known as Angiotensinogenase, is an enzyme involved in the renin–angiotensin aldosterone system (RAAS), which regulates the body’s water balance and blood pressure level. The system regulates the extracellular volume in the blood plasma, lymph and interstitial fluid, as well as controlling constriction of the arteries and blood vessels.[5] It is secreted by the kidney from specialized cells called granular cells and has a fundamental role in hypertension development. Over activation of this system contributes to hypertension and associated end-organ damage.[4]

    The secretion of renin is stimulated by the following three factors:

      • When a fall in arterial blood pressure is detected by pressure sensitive receptors (baroreceptors) in the arterial vessels.
      • When a decrease in sodium chloride (salt) is detected in the kidney by the macula densa in the juxtaglomerular apparatus.
      • When sympathetic nervous system activity is detected through beta1 adrenergic receptors.[4]
