      • Good's buffer solution; pH 6.3
      Specimen Collection & Preservation
      Collect sample using standard sampling tube. Serum, EDTA treated or sodium heparinized plasma are the recommended specimens. Patients are not required to fast prior to blood collection.

      Serum or plasma should not remain at 15- 30C for more than 14 hours. If assay is not completed within 14 hours, serum or plasma may be stored at 2 - 8C upto 1 week. If specimens need to be stored for more than 1 week, they may be preserved at less than -70C upto 3 months.


      Fully automated systems automatically calculate the LDLC concentration of each sample

      Result in mmo1/1 = Result in mgdl x 0.02586

       Application Sheets

      Application sheets for the popular fully automated analyzers are provided along with the kit. For additional system applications, contact our local Accurex representative.


      For calibration, it is recommended to use T LDL C Calibrator from Accurex. Other commercially available LDL-C calibrators have not been tested with this assay and cannot be supported by Accurex Biomedical Pvt. Ltd. Refer to the T LDL-C Calibrator kit package insert for a description of assignment procedures and instructions. The value of the T LDL C Calibrator was assigned by procedures traceable to National Reference System for Cholesterol (NRS/CHOL). Calibration material have concentrations around the medical decision level.

      Calibration frequency :

      Re calibration is recommended

      • Whenever the reagent lot is changed
      • As per the requirements of quality control procedures

      Quality Control

      Each batch of AutoPure T LDL C is assayed with multiple quality control sera prior to release.

      To ensure adequate quality control, it is recommended that the laboratory should use a normal and an abnormal commercial reference control serum. It should be realized that the use of quality control material checks both reagent and instrument functions together. The value of these controls should fall within the specified limits. If control values fall outside specified limits, each of the below criteria should be cross-checked and corrected :
      • Proper instrument function wavelength setting, light source and temperature control
      • Cleanliness of probes & cuvettes
      • Bacterial contamination of wash water used by the instrument
      • Expiry date of the reagent kit

      Expected Values


      The following NCEP cutpoints for patient classification are used for the prevention and management of coronary heart disease :


      <130 mg/dl ( 3.36 mmol/l)


      130-159 mg/dl ( 3.36-4.11 mmol/l)

      High Risk

      >160 mg/dl (4.14 mmol/l)


      Expected range varies from population to population. It is therefore  recommended that each laboratory should establish its own normal range.

      Performance Characteristics Linearity

      With AutoPure T LDL C  the assay is linear upto

      450 mg/dl (11.637 mmo1/1). Determine samples with higher concentrations via the rerun function. On analyzers without rerun function, manually dilute sample with higher concentrations using 0.9% NaCI or distilled / deionized water (e.g. 1 + 4). Multiply the result by the appropriate dilution factor (e.g. 5).


      There is no significant interference in samples containing upto 20 mg/dl of conjugated & unconjugated bilirubin, 1293 mg/di of triglycerides, 500 mg/dl of haemoglobin, 50 mg/di ascorbic acid & 5000 mg/dl gamma globulins


      Reproducibility was determined using three levels of pooled human sera as shown below 

      Within run

      Between run

      Mid (130-159 mg/dl)







      High (>160 mg/dl)
