INTRODUCTION Assay kit Qualitative is intended for detection of hepatitis C virus (HCV) RNA in patient plasma and serum. The method is based on the reverse transcription of viral RNA to generate complementary DNA (cdna), with subsequent amplification of target cdna by Polymerase Chain Reaction (PCR) with fluorescent detection of amplified DNA in the realtime mode. Assay kit Qualitative is intended for use in conjunction with clinical practice for diagnosis of hepatitis C disease and for highly sensitive screening of donor serum (plasma). Page 4 of 12

5 The assay kit is adapted for real-time PCR detection systems like iq icycler, iq5 icycler, CFX96 (Bio-Rad, USA), DT-96 (DNA-technology, Russia); «Rotor-Gene 3000 и Rotor-Gene 6000 (Corbett Research, Australia) or their analogues. The kit contains reagents sufficient for 4 times 12 test runs, which may be performed separately or simultaneously. It is strongly recommended to use one Positive Control sample and one Negative Control sample in each test run. Assay kit can be used with either of two specimen preparation procedures, the Standard procedure or the UltraSensitive procedure. For the Standard specimen preparation procedure, HCV RNA is isolated from 100µl of serum (plasma). In the UltraSensitive specimen preparation procedure, HCV viral particles in serum (plasma) are concentrated by Concentrating Solution of 1 ml of serum (plasma). Specificity Assay kit is designed for in vitro determination of the HCV genotypes 1a, 1b, 2a, 2b, 2c, 2i, 3, 4, 5a, 6 regardless of subtype. The samples containing HIV RNA with concentration above the detection limit will be determined as positive. If the specimen does not contain HIV RNA, analysis will give negative result (in 100% of cases). Sensitivity The assay kit securely determines HCV RNA in concentration not less than 15 IU/ml for UltraSensitive specimen preparation procedure (or not less than 150 IU/ml for the Standard procedure). 4. PRINCIPLES OF THE PROCEDURE Principle of analysis is based on isolation of nucleic acids directly from serum (plasma) jointly with preliminarily added Internal Control, the reverse transcription of viral RNA with subsequent PCR amplification of target cdna by PCR with fluorescent detection of amplified DNA in the real-time mode. For the convenience of the user it is recommended to use a magnetic rack through workout of the Extraction of RNA. Specimen preparation for 1ml or 100 µl of serum (plasma) is allowed 5. PRECAUTIONS Wear protective disposable gloves, laboratory coats and eye protection when handling specimens and kit reagents. Avoid microbial and ribonuclease contamination of reagents when removing aliquots from reagent vials. The use of sterile disposable pipettes and RNase-free pipette tips is recommended. Do not pool reagents from different lots or from different vials of the same lot. Page 5 of 12

12 Click «More Settings» (Outlier removal) button, determine NTC threshold value as 5% In the column «CT Calculation» (right part of the window) determine «Threshold» value as 0, In the result table («Quant. Results» window) Ct will be displayed In Positive Control sample the program should detect: ROX fluorescent signal increase and Сt value (HCV cdna amplification); FAM fluorescent signal increase and Сt value (IC cdna amplification) In Negative Control sample the program should detect: FAM fluorescent signal increase and Ct value, and no significant ROX fluorescent increase should appear. If Ct value for NC along ROX channel is less than 40, this indicates the presence of contamination The program should detect amplification signal increase for IC cdna (channel FAM) in each sample and define Ct for IC. Probe analysis is valid if Ct of IC for this sample is equal to or less than In the case of contamination (when NC is determined as positive) all positive results in this test should be repeated from the RNA extraction stage. Negative samples of such test run are considered reliable Calculate (IC Ct) m as the average Ct value of IC for all samples (including PC and NC). Samples with Ct of IC, that differ from (IC Ct) m by more than 2 cycles, should be ignored. After screening, recalculate (IC Ct) m for remaining samples The sample is considered negative if Ct value along the ROX channel exceeds 40 or is not determined. If Ct of IC for this sample differs from (IC Ct) m by more than 2 cycles, then the result for this sample should be considered as equivocal. The test should be repeated from the RNA extraction stage. The sample is considered positive if Ct value along the ROX channel does not exceed 40. If Ct of IC for this sample differs from (IC Ct) m more then 2 cycles, the sample is considered as borderline and have to be checked properly The test results are considered reliable only when Positive and Negative controls perform as expected.
