HIV Test

 

Background
 

An HIV infection may proceed asymptomatic for many years. Symptoms occur primarily in advanced disease and sometimes a few weeks after infection (called primary infection).

 

It is important to diagnose HIV infection with a HIV test as early in the process as possible, both to the patient can be monitored optimally and receive treatment when this is indicated, partly from infectious disease standpoint.

Primary HIV Infection
 

Symptoms
 

  • Symptoms of primary HIV infection is detected in> 50% of infected patients.
  • Symptom onset 1-4 weeks after infection (usually about 2 weeks).
  • Duration of symptoms is usually 1-2 weeks (sometimes just a few days and sometimes up to a month).
  • Often mononucleosis illness with fever, pharyngitis (sometimes with ulceration of the oral mucosa and throat) and lymph node enlargement.
  • More than 50% have a rash (macular red efflorescence) on the upper part of the chest and back, sometimes on the face, arms and thighs).
  • Serous meningitis / meningoencephalitis sometimes occur.

 


laboratory HIV test
 

  • Anaemia, leucopenia and thrombocytopenia are common
  • Often seen elevated liver enzymes (AST and ALT)
  • CRP is normal or slightly elevated

 

Diagnostics and HIV test.


 HIV serology: HIV Ab / Ag Combo HIV Test at home. At strong suspicion blood sample   
      
 It takes one to a few weeks before HIV antibodies begin to form. If the sampling is done early in the process can antibody tests show "false" negative results. In these cases, often the antigen test is positive if the patient is symptomatic primary HIV infection. HIV RNA by PCR will be positive even earlier in the process and can exceptionally be the strong suspicion of primary HIV infection.

 

Our new HIV 5th generation HIV test It is the only legally approved, FDA, CE-marked, WHO, device available for HIV testing at home, and is over 99% accurate from 14 days after suspected exposure to HIV infection.

 

Symptomatic HIV Infection

Apart from primary infection is an HIV infection is usually asymptomatic until the number of T-helper cells (CD4 + cells) decreased to less than 350 x 106 / L. The duration of the asymptomatic stage of the disease can vary from a few years to> 10-15 years. The higher the viral replication (can be measured by quantitative HIV RNA PCR in plasma), the faster decline in CD4 cells and disease progression to AIDS.

 

"Early" symptoms

 

  • Candida stomatitis
  • Varicella zoster
  • seborrheic dermatitis
  • Hairy leukoplakia on the tongue

 

Later symptoms

 

  • Weight loss, fatigue, night sweats
  • recurrent pneumonias
  • chronic diarrhea
  • Other AIDS-defining diagnosis (see Classification of HIV infection)

 

Indicators of HIV Infection
 

2/3 of newly diagnosed HIV in Canada is called "late presenters", CD4 <350, many have sought medical care in the past where HIV diagnosis overlooked. By expanding HIV testing for indicator diseases where the expected prevalence is relatively high, more undiagnosed HIV infections diagnosed.

 

Indicator Diseases is expected HIV prevalence> 0.1% of the Canada population

 

Example:

 

  • STI, chlamydia, gonorrhea, syphilis, genital ulcers
  • Tuberculosis
  • Lymphoma, all types
  • Cervical and anal cancer / dysplasia
  • Herpes zoster at age <65 years
  • Hepatitis B and C, chronic or acute
  • Mononucleosis symptoms
  • Anemia, thrombocytopenia and leucopenia> 4 weeks
  • Seborrheic dermatitis / oral candidiasis

 

A person can be infected with HIV virus and not show any symptoms, a HIV test at home is the only way to know for sure and be absolute anonyms.  At canadahometest.com do we offer the latest HIV 5th generation HIV test.
