<\/span><\/h2>\nDNA tests <\/span><\/i>are highly accurate, showing up to 99% or more accuracy; however, the results might be wrong in a few cases due to certain factors<\/span><\/i>. These include:<\/span><\/p>\n<\/span>Human Error<\/span><\/span><\/h3>\nImproper data entry, mislabeled samples, and mix-ups of the results at the lab can result in wrong DNA test results.<\/span><\/p>\n<\/span>Sample <\/span>Contamination<\/span><\/span><\/h3>\nWhile collecting samples, contamination can occurrwhic results in mixing the DNA samples this ensuring flawed results.<\/span><\/p>\n<\/span>Chimerism<\/span><\/span><\/h3>\nChimerism<\/b> happens when one individual has two different sets of DNA. This makes paternity or maternity outcomes incorrect.\u00a0<\/span><\/p>\n<\/span>Identical Twins<\/span><\/span><\/h3>\nIdentical twins have similar DNA samples, making it difficult for analysts to distinguish between them. Thus, the results are defective.<\/span><\/p>\n<\/span>Mutation or Mosaicism<\/span><\/span><\/h3>\nBiological factors like non-standard genetic mutations or mosaicism can interfere with parental identification.<\/span><\/p>\n<\/span>Limited or Incomplete Databases<\/span><\/span><\/h3>\nThe accuracy of results relies on the diversity and size of the database as well.A database of a small size can lead to wrong or incorrect results.<\/span><\/p>\n
