HSV (Herpes Simplex Virus) Detection Test

The herpes simplex virus, also known as HSV, is an infection that causes herpes. Herpes can appear in various parts of the body, most commonly on the genitals or mouth. There are two types of the herpes simplex virus: HSV-1: primarily causes oral herpes, and is generally responsible for cold sores and fever blisters around the mouth and on the face. HSV-2: primarily causes genital herpes, and is generally responsible for genital herpes outbreaks. The herpes simplex virus is a contagious virus that can be transmitted from person to person through direct contact. Children will often contract HSV-1 from early contact with an adult who has an infection. They then carry the virus with them for the rest of their lives. Some of the symptoms associated with this virus include: blistering sores (in the mouth or on the genitals), pain during urination (genital herpes), itching, fever, swollen lymph nodes, headaches, tiredness, lack of appetite. HSV can also spread to the eyes, causing a condition called herpes keratitis. This can cause symptoms such as eye pain, discharge, and a gritty feeling in the eye.

DiAGSure CMV detection kit

CMV or Herpesvirus 5, a common virus, spreads from person to person through body fluids, such as blood, saliva, urine, semen and breast milk. The symptoms include premature birth, low birth weight, jaundice, hepatomegaly, microencephaly, purple skin patches or rash, splenomegaly, pneumonia and seizures. Endogenous IC enables proper sample quality check. Positive control (PC) is so provided that a customer can run a PC per 10 samples (or per 5 samples by half-dilution of PC).
  • Specimen type: blood (mostly), urine, sputum, amniotic fluid, cerebrospinal fluid, duodenal fluid, and other body tissues.
  • Technology: 2-plex TaqMan PCR (one for target, other for internal control)
  • Coverage: All strains of CMV
  • Turn-around-time: 1hr
  • Sensitivity: 3 copies of in vitro cloned viral UL54 DNA polymerase gene construct.
  • Specificity: 100%
 

DiAGSure Panfungal Detection Kit

The prevalence of fungal infections has increased in recent years due to an increasing population of immune-compromised patients, intensive immunosuppressive chemotherapy, increasing awareness of fungal infections, and the widespread use of broad-spectrum antibiotics and central venous catheters. The panfungal PCR assay can detect multiple fungal genera and may be used as an adjunct to conventional methods for the detection of fungal infection or for describing the natural history of fungal infection. Further studies are needed to define the sensitivity and specificity of this assay for the diagnosis of fungal infection prior to the existence of other clinical or laboratory indications of invasive fungal infection.
  • Symptoms of panfungal included Skin changes including red and possibly cracking or peeling skin, itching, redness and soreness on and surrounding the vagina. A red rash with a circular shape and rise edges, redness in the groin, buttocks, or thighs, chafing, irritation, itching, or burning in the infected area, Invasive fungal infections (IFIs) affect a multitude of organs leading to meningitis, sinusitis, osteomyelitis and enteritis.
  • Species coverage : 95%.
  • Sample type: Bronchoalveolar lavage (BAL), tracheal aspiration, sputum, nasal/oral swab in VTM, tear, pleural fluid, paraffin embedded tissue samples (FFPE), skin or nail swab, biopsy, blood and serum samples .
  • Minimum sample volume: 1 mL
  • Technology: 2-plex TaqMan PCR (one for target, other for internal control)
  • Turn-around-time: 48 hrs
  • Test Sensitivity: 10 copies of in vitro cloned fungal 18S rDNA.
  • Specificity: 99%

DiAGSure Chlamydia trachomatis Detection Kit

Chlamydia trachomatis is a gram-negative bacterium that infects the columnar epithelium of the cervix, urethra, and rectum, as well as non-genital sites such as the lungs and eyes. Most persons with this infection are asymptomatic. Untreated infection can result in serious complications such as pelvic inflammatory disease, infertility, and ectopic pregnancy in women, and epididymitis and orchitis in men. Men and women can experience chlamydia-induced reactive arthritis.
  • Signs and symptoms of Chlamydia trachomatis infection can include: Painful urination, vaginal discharge in women, discharge from the penis in men, painful sexual intercourse in women, bleeding between periods and after sex in women, testicular pain in men.
  • Sample type: urine and genital swab samples.
  • Technology: 2-plex TaqMan PCR (one for target, other for internal control)
  • Minimum sample volume 1 mL
  • Turn-around-time: 1 hr
  • Test Sensitivity: 30 copies of in vitro cloned Chlamydia trachomatis ompA gene construct.
  • Specificity: >=99%
