E-lyte Plus Advanced Electrolyte Analyzer

E-lyte Plus Advanced Electrolyte Analyzer

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Sodium (Na+) and Potassium (K+) Measurement for Fluid and Electrolyte Disorders

• Primary Use: Provides a fully automated, microprocessor-controlled electrolyte analyzer using Ion Selective Electrode (ISE) technology to measure sodium (Na+) and potassium (K+) concentrations in whole blood, serum, plasma, and urine . Multiple electrodes (up to 6) can be installed simultaneously, with test times ranging from 30-40 seconds .

• How it helps: For the nephrologist, emergency physician, and intensive care specialist, the E-lyte Plus delivers critical sodium and potassium values essential for diagnosing and managing hyponatremia, hypernatremia, hypokalemia, and hyperkalemia—electrolyte disturbances that can cause cardiac arrhythmias, neuromuscular irritability, seizures, and coma. For the patient with heart failure on diuretics, chronic kidney disease, adrenal insufficiency (Addison’s disease), or severe diarrhea/vomiting, accurate sodium and potassium measurement guides life-saving interventions such as electrolyte replacement, fluid resuscitation, and medication adjustment to prevent fatal cardiac arrhythmias.

2. Chloride (Cl-) and Anion Gap Calculation for Acid-Base Disorders

• Primary Use: Measures chloride (Cl-) concentration, enabling calculation of the anion gap for evaluation of metabolic acidosis and alkalosis in critically ill patients . The analyzer simultaneously processes up to six installed electrodes for comprehensive electrolyte panels .

• How it helps: For the pulmonologist, intensivist, and nephrologist, the anion gap (calculated from Na+, K+, Cl-, and bicarbonate) distinguishes between high anion gap metabolic acidosis (diabetic ketoacidosis, lactic acidosis, toxic alcohol ingestion, uremia) and normal anion gap metabolic acidosis (diarrhea, renal tubular acidosis). For the patient with diabetic ketoacidosis, acute kidney injury, sepsis, or ethylene glycol poisoning (antifreeze ingestion), rapid anion gap assessment enables accurate diagnosis of the underlying acidosis, guiding bicarbonate therapy, insulin administration, dialysis, or antidote administration to prevent life-threatening metabolic decompensation.

3. Ionized Calcium (Ca++) and pH Measurement for Critical Care and Parathyroid Disorders

• Primary Use: Measures ionized calcium (Ca++) and pH (hydrogen ion concentration) in whole blood, serum, and urine samples, offering simultaneous multiple electrolyte analysis . The system includes automatic ISE calibration and 3-level QC with Levey-Jennings charting .

• How it helps: For the endocrinologist, critical care physician, and surgeon, the E-lyte Plus provides ionized calcium (the biologically active form of calcium) for diagnosing and monitoring hypercalcemia (primary hyperparathyroidism, malignancy) and hypocalcemia (hypoparathyroidism, critical illness, post-thyroidectomy). For the patient with suspected primary hyperparathyroidism (kidney stones, osteoporosis, fatigue), ionized calcium measurement confirms the diagnosis before parathyroid surgery. For the post-thyroidectomy patient, ionized calcium monitoring detects hypocalcemia (parathyroid injury), enabling timely calcium and calcitriol replacement to prevent tetany, laryngospasm, and seizures.

4. Lithium (Li+) Monitoring for Psychiatric Medication Management

• Primary Use: Measures lithium (Li+) concentration in serum for therapeutic drug monitoring (TDM) of patients receiving lithium carbonate for bipolar disorder .

• How it helps: For the psychiatrist and primary care physician, the E-lyte Plus provides accurate serum lithium levels for patients on long-term lithium therapy—a medication with a narrow therapeutic index (0.6-1.2 mEq/L) where levels above 1.5 mEq/L cause toxicity (nausea, tremor, confusion, seizures, coma, cardiac arrhythmias) and levels below 0.6 mEq/L risk mood relapse. For the patient with bipolar disorder, regular lithium level monitoring ensures therapeutic efficacy while preventing life-threatening lithium toxicity, enabling safe long-term management of this chronic mental health condition.

SECONDARY & SUPPORTIVE USES

1. Emergency Department and Critical Care Stat Testing: Provides rapid (30-40 second) electrolyte results for emergency department and ICU stat orders, essential for resuscitation, cardiac monitoring, and ventilator management.

2. Pre-Operative and Post-Operative Surgical Monitoring: Supports pre-operative electrolyte screening for surgical clearance and post-operative monitoring for fluid and electrolyte shifts following major surgery.

3. Dialysis Unit and Chronic Kidney Disease Management: Monitors pre-dialysis and post-dialysis electrolyte levels (Na+, K+, Cl-, Ca++) in hemodialysis and peritoneal dialysis patients, guiding dialysate prescription and detecting dangerous hyperkalemia requiring urgent dialysis.

4. Cardiology and Arrhythmia Risk Assessment: Evaluates potassium levels in patients on diuretics, digoxin, and antiarrhythmic medications (amiodarone, sotalol); hypokalemia predisposes to torsade de pointes and ventricular fibrillation.

5. Endocrine and Metabolic Disorder Diagnosis: Supports diagnosis of adrenal insufficiency (Addison’s disease: hyponatremia, hyperkalemia), hyperaldosteronism (Conn’s syndrome: hypokalemia, hypernatremia), and diabetes insipidus (hypernatremia assessment).

6. Gastroenterology and Malabsorption Assessment: Evaluates electrolyte losses in patients with chronic diarrhea, vomiting, malabsorption, short bowel syndrome, and gastrointestinal fistulas.

7. Oncology and Chemotherapy Monitoring: Monitors electrolyte levels in cancer patients on chemotherapy regimens causing nausea/vomiting or nephrotoxicity (cisplatin, carboplatin) leading to hypomagnesemia and hypocalcemia.

8. Pediatric and Neonatal Electrolyte Assessment: Measures electrolytes in small-volume pediatric/neonatal samples for evaluation of dehydration, pyloric stenosis (hypochloremic metabolic alkalosis), and congenital adrenal hyperplasia (salt-wasting crisis with hyponatremia, hyperkalemia).

9. Geriatric and Nursing Home Medication Monitoring: Supports electrolyte monitoring for elderly patients on multiple medications including diuretics, ACE inhibitors, ARBs, and potassium supplements, preventing drug-induced electrolyte disturbances.

10. Sports Medicine and Athlete Hydration Assessment: Evaluates electrolyte levels in endurance athletes (marathon runners, triathletes) for hyponatremia (overhydration) and exercise-associated collapse.

11. Pregnancy and Obstetric Complication Monitoring: Monitors electrolytes in hyperemesis gravidarum (severe vomiting causing hypokalemia, hypochloremia) and preeclampsia (electrolyte shifts requiring monitoring).

12. Blood Gas and Acid-Base Interpretation: Integrates electrolyte results with blood gas analysis (bicarbonate calculated from pH and pCO2) for comprehensive acid-base disorder classification.

13. Automatic QC and Quality Assurance: Built-in 3-level quality control with Levey-Jennings charting supports laboratory quality assurance programs, regulatory compliance, and accreditation requirements .

14. LIS Connectivity and Data Management: RS-232 interface enables data export to Laboratory Information Systems; 8,000 test result storage with patient and QC data supports electronic medical record integration .

15. Outpatient Clinic and Physician Office Laboratory Testing: Compact benchtop design (27.9 × 43.8 × 36.8 cm, 9.5 kg) enables electrolyte testing in outpatient clinics, physician offices, and urgent care centers without sending samples to central labs.
