Clinical Utility
A-1-AGP (orosomucoid) is an “acute phase” protein. The concentration of A-1-AGP changes in response to trauma. Acute-phase proteins are rich in carbohydrate and are synthesized by the liver.
Decreased levels of A-1-AGP are associated with:
Estrogen therapy
Severe hepatic damage
Nephrotic syndrome
Malnutrition
Pregnancy

8. QUANTIA A-1-AGP Reaction & Methodology
Step 1: Sample containing A-1-AGP is added to Reagent 1 (Reaction Buffer and polyethylene glycol (PEG)).
Step 2: Reagent 2 containing Antibody (anti-human A-1-acid glycoprotein goat serum) is added to the sample/Reagent 1 mix.
Sample/ Reagent 1
Reagent 2 Y Y Y Y Y + Y Y ↑
A-1-AGP Specific Antibody ↑
A-1-AGP
Step 3: When sample containing A-1-AGP is added to R1 and mixed with the antibody in Reagent 2 insoluble aggregates form. The degree of agglutination is directly proportional to the concentration of A-1-AGP in the sample. This is determined by measuring the decrease of transmitted light caused by the aggregates at a wavelength of 700 nm. Y Y Y Y Y Y Y Y Y

18. QUANTIA A-1-AGP Quality Control
The multi-constituent controls are prepared from human sera containing A-1-acid glycoprotein, alpha-1-antitrypsin, β2-Microglobulin, with gentamicin sulfate as a preservative.
The concentrations are indicated on the corresponding QUANTIA PROTEINS Control value sheet.
The lyophilized controls should be reconstituted with 1 mL of deionized water or equivalent.
The lyophilized controls are stable until the expiration date on the label if stored at 2-8 °C.
Once reconstituted, the controls can be used for 15 days if stored between 2-8 °C.
Do not freeze controls.

19. QUANTIA A-1-AGP Performance Data
Serum and Plasma
Normal Expected Range (adults): 50 to 120 mg/dL (0.5 to 1.2 g/L)
Reportable Range:
15.0 to mg/dL (0.15 to 2.50 g/L)
15.0 to mg/dL (0.15 to g/L) using the on-board dilution protocol
Limit of Quantitation (LOQ) = 15.0 mg/dL (0.15 g/L)
LOQ represents the lowest measurable concentration at which the CV < 20% and the recovery is within +/- 20% of expected value.
Limit of Detection (LOD) = 2.5 mg/dL (0.03 g/L)
LOD is defined as the mean concentration of an analyte-free sample + 2SD, where SD is the within-run standard deviation.
Note: SI units are g/L. To convert results from mg/dL to g/L, multiply by 0.01.
