Question 1

hiv viral load by genexpert a nucleic acid test or not? and how much reliable this test at 2 years after exposure if the result was target not detected. please answer?

Accepted Answer

: At 2 years after exposure a negative 4th gen DUO test is sufficient. You do not need more tests.

Question 2

is gout caused by an error in nucleic acid metabolism that leads to a buildup of uric acid in body fluids?

Accepted Answer

Gout Attack Reason: Uric acid that produces gout is a normal breakdown product of purines (nucleic acids) in our bodies.A gout attack is caused by an excessive buildup of uric acid in the blood stream. Daily uric acid is filtered by the kidneys and passed through our urine. Over a certain concentration, the uric acid crystals leave the blood and collect in a susceptible area (like an arthritic big toe joint).

Question 3

0.9 positive: > 0.9 the cdc recommends that a positive hcv antibody result be followed up with a hcv nucleic acid amplification test what  is this?

Accepted Answer

HCV confirmation: Both HCV antibody test and HCV nucleic acid amplification test (also called HCV RNA by PCR) are blood tests for diagnosing Hepatitis C. HCV antibody is a screening test - it detects the presence of a protein (antibody) that our system has developed against Hepatitis C virus. HCV RNA by PCR test measures directly the presence of Hepatitis C virus in the blood and is a confirmatory test for HCV.

Question 4

what is the window period of nucleic acid testing (nat) for hiv?

Accepted Answer

HIV Testing: Not sure where this comes from. This seems like old testing techniques. The most common acute and accurate testing is called the duo test. Here the antibody and the HIV specific p-29 antigen are tested together.  This test can be 95% accurate by twelve weeks post exposure.

The better, but more expensive, HIV RNA or dna testing can be accurate at 21 days post exposure.

Question 5

is a pcr rna test for hiv the same as a nucleic acid test? a doctor has told me this is no more accurate than a duo test after 28 days post exposure..

Accepted Answer

See below: PCR RNA for HIV and nucleic acid test are the same. Nucleic acids tests are both more sensitive and specific than antibody and antigen (DUO) tests.

Question 6

i had thyroid cancer. high possibility it has spread. thyroid cancer removed which was stage 6. pap smear done & my result show. this nucleic acid amplification test detects fourteen high-risk hpv type (16,18,31,33,35,39,45,51,52,56,58,59,66,68?

Accepted Answer

: Thyroid cancer is not caused by HPV. You do not say which types of HPV were found in your recent Pap smear if any. If HPV was detected or your Pap smear is abnormal, follow your doctor's advice -- but try not to worry. The vast majority of cervical HPV infections do not lead to cancer or other significant health problems.

Question 7

is pcr rna &  nucleic acid test the same. also is dna hiv test the same. which is the best test to take now after a negative 8 months post exposure hiv test using a 4 generation test, still having symptoms like sore throat and body aches. pcr or dna?

Accepted Answer

: If a 4th gen test was negative at 8 months after exposure, you do not have HIV from that exposure. 
It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It would be prudent to see a doctor. 
Wish you good health!

Question 8

how do prions multiply without nucleic acids?

Accepted Answer

Structure change: Prions are abnormally folded versions of normal proteins. When a prion comes into contact with the "normal" version of itself, it changes the normal protein's structure into a prion.

Question 9

what are the functions of nucleic acids?

Accepted Answer

DNA.: Dna is the nucleic acid that contains all the genetic information.  It is transcribed into rna, another nucleic acid when genes are processed to make proteins.  Transfer RNA carries Amino Acids to sites where proteins are assembled.  Other rnas are involved in controlling which genes are turned on (micro rna) and in the structure of ribosomes.  Nas are found in viruses, bacteria, on up to humans.

Question 10

which chromosome is polydactyly found in?

Accepted Answer

Many : OMIM lists 372 genetic loci causing polydactyly. Many are parts of other multiple malformation syndromes and quite a few just affect the fingers or toe, he latter being mapped to chromosomes 4, 7,  and 13.  Nigerians have a high rate of postaxial polydactyly, usually peduncilated postminimi--over 20%, and blacks have about 10 times the rate of Caucasians.  The Japanese have a form of preaxial polydactyly, usually a double terminal phalanx of the thumb, which they regarde as good luck.
