Product Name

  1. Common name: Apolipoprotein A1 (ApoA1) test kit (immunoturbidimetric assay)
  2. English name: ApoA1 Reagent Kit (Immunoturbidimetric Method)

Reagent Ratio

3:1, 4:1, 5:1, common ratio 3:1, other ratios need to be customized

Intended Use

This reagent is used to determine the amount of ApoA1 in human serum or plasma.

Lipids are synthesized in the liver or small intestine, where they are transformed into hydrophilic structures for transport to tissues and organs by forming a series of particles consisting of an outer coating of monolayer proteins (apolipoproteins) and polar lipids (e.g. phospholipids and unlipidated cholesterol) plus an inner neutral lipid core (e.g. triglycerides and cholesterol lipids). Apolipoproteins play an important role in the further metabolism and catabolism of the above mentioned particles. Apolipoprotein A is the major form of high-density lipoprotein (HDL) and to a lesser extent in celiac particles. The main role of Apo A-1 is to activate lecithin-cholesterol fatty acyltransferase (LCAT) and to remove free cholesterol from extrahepatic tissues. Therefore, Apo A-1 can be considered as an antiatherosclerotic indicator, which is negatively associated with risk factors for coronary heart disease. The present findings show that the development of coronary heart disease is negatively correlated with Apo A1 levels and positively correlated with Apo B. Patients with coronary heart disease generally have relatively low Apo A1 levels and relatively high Apo B levels.

Test Principle

ApoA1 in the sample binds to the specific sheep anti-human ApoA1 antibody in the reagent, forming an insoluble immune complex that causes turbidity in the reaction solution, with the turbidity level reflecting the amount of ApoA1 in the sample.

Main Components

Operation steps.

Apolipoprotein A1 (ApoA1) Assay Kit & Bulk Reagents

Reagents and sample volumes can be increased or decreased in proportion to the requirements of different biochemical analyzers.

  1. Calibration procedure.

Landau calibrators are recommended.

  1. QC control procedures.

It is recommended that each laboratory establish its own quality control system and select appropriate quality control products for quality control. The measured values of QC products should be within the specified range. If outside the specified range, it is necessary to take appropriate measures or contact the manufacturer.

  1. Calculation.

5 points are calibrated and the corresponding values are entered. With △A as the vertical coordinate and concentration as the horizontal coordinate, the standard curve is plotted, and this standard curve is corrected by the non-linear method Spline, Logit-Log4P and other modes, and this standard curve is saved and used to calculate the results.

Positive Judgment Value Or Reference Interval

1.20~1.80 g/L

It is recommended that each laboratory establish its own reference range of normal values.

Interpretation Of Test Results

Bilirubin ≤ 40 mg/dL, hemoglobin ≤ 500 mg/dL and celiac ≤ 500 mg/dL did not interfere with the determination.

Limitations Of The Test Method

The measurement of ApoA1 in human serum or plasma is only one of the indicators used by the clinician to make a diagnosis of the patient. The clinician must also make a comprehensive judgment based on the patient’s physical symptoms, medical history, and other diagnostic items and diagnostic tools.

Product Performance Index

Absorbance of reagent blank: wavelength 340 nm, optical diameter 1.0 cm, temperature 37°C, A0  ≤ 0.15.

Analytical sensitivity: The kit tests 1.00 g/L of the analyte, the absorbance change value ΔA ≥ 0.3.

Linearity range: test serum samples, reagent linearity in the interval of 0.25~2.40 g/L , linear correlation coefficient|r| should not be less than 0.975; in the interval of 0.25~1.00 g/L, the absolute deviation of linearity should not exceed 0.10 g/L; in the interval of (1.00~2.40 g/L, the relative deviation of linearity should not exceed ±10%.

Precision: repeatability CV≤ 5.0%; relative extreme difference between batches≤ 9.0%.

Caution

  1. This product is for in vitro diagnosis only.
  2. Avoid contamination when using the reagent, the container used must be clean, and please take necessary precautions, do not swallow, and avoid contact with skin and mucous membrane.
  3. Please dispose of the measured samples and waste liquids in accordance with the relevant national and local laws and regulations.
  4. For samples with lipid blood visible to the naked eye and triglyceride content exceeding 250 mg/dL, the results need to be diluted with saline before determination and multiplied by the dilution factor.
  5. Please dispose of the measured samples and waste liquids in accordance with the relevant national and local laws and regulations.
  6. When changing the reagent lot number, the calibration should be re-calibrated.
