What is algorithm in HIV testing?
A testing algorithm for serologic diagnosis of HIV-infection is the sequence in which assays are performed to detect HIV antibody in a body fluid. The most common referenced testing algorithm employs an EIA to screen specimens with those found to be positive then confirmed by WB testing.
What is the HIV rate in Ukraine?
HIV epidemic is mixed in Ukraine. Prevalence of HIV among general population is 0.9‐1% and significantly higher among certain key population groups, where epidemic is concentrated: 22.5% among PWID, 5.2% among sex workers (SW), and 7.5% among men who have sex with men (MSM) (IBBS 2017).
What is the most definitive test for detecting HIV?
The primary tests for diagnosing HIV and AIDs include: ELISA Test ELISA, which stands for enzyme-linked immunosorbent assay, is used to detect HIV infection. If an ELISA test is positive, the Western blot test is usually administered to confirm the diagnosis.
Can HIV be detected 10 days after exposure?
A nucleic acid test (NAT)can usually tell you if you have HIV infection 10 to 33 days after an exposure. An antigen/antibody test performed by a laboratory on blood from a vein can usually detect HIV infection 18 to 45 days after an exposure.
How accurate is HIV test after 3 months of exposure?
Tests 3 months after exposure should be 99% accurate. If you are having symptoms of HIV, see your doctor right away. Your doctor may want to use a test that can look for the virus directly in your body.

How accurate is HIV test after 15 days?
The sensitive tests (at least 50 copies/ml) become positive after 10-15 days and ultrasensitive ones (at least 1-5 copies/ml) already after the 5th day of possible exposure. HIV RNA test has 90% accuracy if tested after 10-12 days.
What is the difference between serial and parallel testing algorithm?
Parallel testing means samples are tested simultaneously by two different tests. Serial testing means samples tested by a first test. The results of the first test determine whether additional testing is required.
How are algorithms tested?
Testing an algorithm Trace tables help a programmer to determine the point in a program or algorithm where an error has occurred. Each instruction has been given a line number (1-8). Next, the program is tested using test data. If the numbers 5, 7 and 9 are input, the resulting total should be 21.
