A Small, Dedicated Nephelometer for Measuring IgG, IgM, And Albumin

Community Hospitals & Critical Access Hospitals (CAHs)

• Limited Lab Resources: These facilities often lack large, high-throughput automated analyzers due to space/budget constraints. A small nephelometer provides essential protein testing without a major capital investment.

• Moderate Test Volume: They handle enough IgG/IgM/albumin tests (e.g., 10–50/day) to justify in-house testing but not enough to require a full-scale immunology module on a core lab system.

• Clinical Needs:

• Albumin: Monitoring malnutrition, liver disease, kidney dysfunction (nephrotic syndrome), or critical illness.

• IgG/IgM: Diagnosing infections (e.g., acute vs. past exposure), evaluating immune deficiencies, or screening for autoimmune conditions (e.g., lupus, rheumatoid arthritis).

• Avoiding Send-Out Costs: Sending these tests to reference labs adds 24–72 hour delays and per-test fees. In-house testing speeds up treatment (e.g., sepsis workups, malnutrition intervention).

2. Specialized Outpatient Clinics

• Nephrology/Renal Clinics: Frequent albumin testing for chronic kidney disease (CKD) monitoring.

• Immunology/Rheumatology Clinics: Tracking IgG/IgM in autoimmune diseases (e.g., SLE, vasculitis) or immunodeficiency disorders (e.g., CVID).

• Oncology Clinics: Monitoring albumin for nutritional status during chemotherapy; Ig testing for paraprotein screening (e.g., multiple myeloma).

• Why small? These clinics prioritize space efficiency and targeted testing over broad panels.

3. Rural/Remote Hospitals & Field Hospitals

• Geographic Isolation: Where sending samples to distant reference labs causes critical delays (e.g., diagnosing sepsis via IgM spikes or assessing dehydration via albumin).

• Portability: Compact nephelometers can be deployed in mobile clinics or disaster-response settings.

4. Urgent Care Centers with Lab Services

• Rapid assessment of dehydration (albumin), acute infections (IgM), or chronic disease exacerbations.

GPP-100 POCT Specific Protein Analyzer

The GPP-100 is an automated specific protein analyzer from Goldsite Diagnostics Inc., designed for point-of-care and small laboratory use. It employs nephelometry-based immunoassay technology for quantitative measurement of various proteins in serum or plasma.

Key Features

• Technology: Classical Immunoassay Technology using Nephelometry for reliable, quantitative results.

• Cartridge System: All-in-one cartridge for single tests, with auto-ID via QR code on the reagent cartridge for easy reagent recognition and calibration.

• Sample Handling: Small sample volume (typically 10-20 µL, depending on assay); supports serum, plasma, or other compatible fluids.

• Test Menu: Wide range including Glycated Hemoglobin (HbA1c), CRP (C-Reactive Protein), Complement 3 (C3), Complement 4 (C4), and more assays in development (e.g., for inflammation, immune diseases).

• Calibration: Independent calibration per cartridge; maintenance-free operation.

• Operation: One-step process – insert cartridge, add sample, and run. No complex setup required.

• Throughput: Rapid measuring time (results in approximately 3-5 minutes per test, based on standard nephelometry cycles).

• Compliance: CE-certified for EU markets; registered in multiple global regions as of 2025.
