Enterovirus detection


Introduction: Enteroviruses are a group of viral agents that inhabit the intestine and are responsible for important and frequent human diseases with very varied clinical manifestations. It is a causative agent of meningitis in immunosuppressed patients. About the exam: In the PCR diagnostic test, certain conserved regions of enterovirus RNA are amplified exponentially. Therefore, from a small number of copies of this sequence, millions of fragments are produced that are easily detectable, providing fast results with high reliability. Genes or alleles analized: Enterovirus region Technique used: Real Time Sample type: Whole blood (EDTA, hemogram tube), 2.5 mL // Amniotic fluid, 2mL // Cerebrospinal fluid, 1mL // Plasma, 1mL Results delivered in: 2 business days In case you have any questions, get in touch.




Toxoplasmosis detection


Introduction: Toxoplasma gondii is a species of protozoan parasite that causes toxoplasmosis, a disease that is generally mild, but can be complicated to become fatal, especially in human fetuses. It is a causative agent of meningitis in immunosuppressed patients. About the exam: The study consists of amplifying a conservative region of Toxoplasma Gondii by means of RT-PCR in real time; with an efficiency greater than 95% in detection of up to 100 copies. Genes or alleles analized: Toxoplasmosis Technique used: Real Time Sample type: 2.5mL of sange in tube with EDTA, consult for others. Results delivered in: 2 business days In case you have any questions, get in touch.




Chikungunya virus detection by RT- PCR


Introduction: Virus of the family Togaviridae CHKV (Chikungunya). They are called Arboviruses because they are transmitted by haematophagous atropods, in this case all three are transmitted by the same vector; the Aedes Aegypti mosquito. Usually the Zika virus causes mild symptoms that usually manifest a few days after the bite of an infected mosquito. Although most infected people will not have symptoms, some may have conjunctivitis, muscle and joint pain and fatigue, symptoms that persist for 2 to 7 days.
There are no differences between the symptoms of pregnant women infected with Zika virus and non-pregnant infected women. About the exam: The study consists on amplifying chikungunya by RT-PCR in real time; with an efficiency greater than 95% in detection of up to 100 copies.

Dengue virus detection by RT-PCR


Introduction: Virus of the family Flaviridae DENV (Dengue)
They are called Arboviruses because they are transmitted by haematophagous atropods, in this case they are transmitted by the same vector; the Aedes Aegypti mosquito.
Severe dengue (formerly known as dengue hemorrhagic fever) was first identified in the 1950s during an epidemic of the disease in the Philippines and Thailand. Today, it affects most of the countries of Asia and Latin America and has become one of the main causes of hospitalization and death in children and adults in these regions. About the exam: RT-PCR en tiempo real; con una eficiencia mayor al 95% en deteccion de hasta 100 copias. Genes or alleles analized: Dengue: Deteccion de Subtipos 1, 2, 3 and 4 Technique used: Real Time Sample type: Whole blood (EDTA, hemogram tube), 2.5 mL // Plasma, 1mL Results delivered in: 2 business days In case you have any questions, get in touch.




Parvovirus detection


Introduction: The human parvovirus B19 is associated with various diseases such as infectious erythema and sporadic or epidemic infections. About the exam: Study for the detection of human parvovirus B19 using the Real Time PCR technique. Genes or alleles analized: Parvovirus Technique used: Real Time Sample type: Whole blood (EDTA, hemogram tube), 2.5 mL // Plasma, 1mL Results delivered in: 2 business days In case you have any questions, get in touch.




HCV genotyping


Introduction: The different genotypes of HCV generally act the same in the way of infecting a person and causing disease. But HCV genotypes respond differently to treatment with HCV medications. About the exam: Viral genotyping of HCV is used to determine which HCV genotype is present. HCV has 6 genotypes, and some are easier to treat than others. Genes or alleles analized: HCV Genotype Technique used: Sanger Sample type: Whole blood (EDTA, hemogram tube), 2.5 mL // Plasma, 1mL Results delivered in: 10 business days In case you have any questions, get in touch.




Hepatitis C virus detection (HCV)


Introduction: The infection of Hepatitis C Virus (HCV) affects approximately 3% of the world's population, and constitutes one of the main causes of chronic liver disease. About the exam: The HCV genetic material (RNA) test uses the polymerase chain reaction (PCR) to identify an active hepatitis C infection. The quantitative HCV test (also called viral load) is used before and during treatment to know how much treatment time is necessary and to check how well the treatment is working. Genes or alleles analized: HCV Technique used: Real Time Sample type: Whole blood (EDTA, hemogram tube), 2.5 mL // Plasma, 1mL Results delivered in: 7 business days In case you have any questions, get in touch.




HIV tropism test


Introduction: When HIV binds to a CD4 cell that it is going to infect, it uses molecules from the surface of the cell. These are called co-receptor receptors or chemokines. The first receptor that HIV uses is the CD4 molecule. The virus then uses a "co-receptor". This can be a CCR5 or CXCR4 molecule.
The virus usually uses one or another type of coreceptor. The HIV that uses the CCR5 co-receptor is called "tropic for CCR5" or "tropic R5". However, viral tropism may be CCR5, CXCR4 or "double / mixed" (D / M) if some of the virus samples use each coreceptor. The virus in recently infected persons is usually tropic CCR5. When HIV infection progresses, tropism usually changes to include more tropism CXCR4. About the exam: The tropism test is used to decide if a CCR5 blocker will be useful in controlling the patient's HIV. Currently a tropism test is required before prescribing maraviroc.

Herpes virus detection (CMV, EBV, HSV1 and 2, HSH, VZV)


Introduction: The family Herpesviridae is the cause of different disorders depending on type:

  • VHH-2: Produces genital herpes, which causes vesicles and then genital ulcers.
  • VHH-3: It is the varicella-zoster virus (VZV), which produces shingles (shingles or culebrine) and chickenpox, a very contagious disease, especially in children.
  • VHH-4: It is the Epstein-Barr Virus (EBV), which causes infectious mononucleosis, Burkitt's lymphoma and nasopharyngeal carcinoma.
  • VHH-5: It is the cytomegalovirus (CMV), which also causes mononucleosis, retinitis, hepatitis and other infectious diseases especially in immunosuppressed.
  • VHH-6: It is the roseola infantum virus, sudden exanthema of childhood.
  • VHH-7: Similar to VHH-6, with similar symptoms.
  • VHH-8: Kaposi's sarcoma virus, is a Rhadinovirus
About the exam: Study for the detection of 6 types of viruses belonging to the Herpes family that cause diseases in humans, these are Herpes simplex Type 1 (HSV-1), Herpes simplex Type 2 (HSV-2), Varicella zoster ( VZV), Epstein-Barr (EBV), Cytomegalovirus (CMV), Roseolovirus (HHV-6).
