Specimen Stability Information
Specimen Type | Temperature | Time | Special Container |
Whole Blood | Ambient | 2-3 days | |
Refrigerated 2 to 8 degrees | 6 days |
Useful For • Detection and quantification of HIV-1 DNA in blood of patients with HIV infection (i.e., sero-positive) • Monitoring disease progression in chronic HIV infection • Monitoring response to long-term ARV treatment and its effect on HIV latency.
Test Details: Method: Quantitative Real-time PCR using Taqman technology. Specificity: Assay is designed with specific primers and Taqman probe for in vitro quantification of all the genetic subtypes of HIV-1 group M against the LTR gene. Target Selected: HIV-1 LTR, Highly conserved sequence among HIV-1 group M is selected for detection. Sample: EDTA Whole Blood. Limit of detection: 100 copies/ml. Measuring Range: 100 – 100 Million copies/ml. PCR system: CFX96™ Real-time PCR System-IVD (BIORAD). Software: Bio-Rad CFX Manager IVD Edition 1.6. Data Analysis Mode: PCR Quantification with standard curve.
Test Interpretation: HIV Proviral DNA Real-time PCR is done by using specific primers and sequence-specific Taqman Probe to conserved regions of HIV-1 Proviral DNA that exclude the HIV-2 infection. HIV-1 standard, Negative control, and Internal controls are run along with duplicates of patient samples to ensure more accurate and precise detection of Proviral HIV-1 DNA with least variation. “Detected” results indicate the presence of HIV-1 infection. Two consecutive positive HIV-1 proviral DNA test results are necessary for the Diagnosis of HIV-1 infection in infants <2 years of age also for Patients. “NOT Detected” indicates either the absence of HIV-1 Proviral DNA in the patient’s Specimen or HIV-1 Proviral DNA level is below the detection limit of this assay.
Copies/105 cells | Interpretation |
Not Detected | Absence of HIV-1 DNA in patient’s Specimen |
Detected | Presence of HIV-1 DNA in patient’s Specimen |
Less than 100 | HIV-1 DNA Detected above the linear range of the assay |
100 to 105 | HIV-1 DNA Detected within the linear range of the assay |
Clinical Significance: Proviral Human Immunodeficiency Virus type-1 (HIV-1) proviral DNA is increasingly used to measure the HIV-1 cellular reservoirs, a helpful marker to evaluate the efficacy of antiretroviral therapeutic regimens in HIV-1–infected individuals. Furthermore, the proviral DNA load represents a specific marker for the early diagnosis of perinatal HIV-1 infection and might be predictive of HIV-1 disease progression independently of plasma HIV-1 RNA levels and CD4+ T-cell counts. The quantification indicates either the cell-associated HIV DNA or HIV DNA+ cell or HIV Proviral Load. DNA levels were calculated and expressed as copies per milliliter of whole blood. HIV-1 DNA levels in whole Blood were measured at baseline (prior to initiation of study treatment) and at weeks 16, 32, 48, 64, 80, and 96. Note: The linear dsDNA molecule is the precursor to the provirus. HIV infection of target cells generates a number of nonintegrated DNA species. These unintegrated HIV-1 DNA forms, which are linear or circularized, arise when viral dsDNA fails to integrate into the host genome, or linear unintegrated HIV-1 DNA may form. Therefore, aside from proviral DNA (HIV-1 dsDNA integrated into the host genome), several unintegrated forms also persist intracellularly. It is worth mentioning that cell-associated HIV-1 DNA can be found in both actively and latently infected cells. The new technique was developed to quantify proviral HIV-1 and all other forms of HIV DNA present intracellularly using a TaqMan real-time PCR assay.
Limitation of Assay: The prime reason for paradoxical results is contamination during specimen collection, inappropriate selection of specimen, presence of inherent PCR inhibitors, loss, or degradation of DNA.
