DNA Paternity Testing Procedures: Buccal Swab Test Versus DNA Hair Testing

DNA testing has many applications across a broad array of disciplines and industries. DNA profiling is used to establish the identity of individuals largely for forensic purposes and for use in law enforcement services. Personal identification and kinship analysis as well as family relatedness are also popular forms of DNA analysis.
A recent study determined that 1 in 10 Americans ponder questions related to paternity. Establishing a biological relationship between parent and child is significant. Whether for financial support, immigration requirements, emotional reasons, health care tracking, peace-of-mind or even legal situations paternity testing can provide the needed answers.
There are several types of DNA paternity testing procedures:
DNA Blood Test
Paternity testing procedures have historically been conducted in hospitals and laboratories under prior authorization and using a blood draw for specimen.
Today, home paternity testing kits are available at local drug stores across the country. These kits can be used for peace-of-mind and for legal (court-admissible) reasons-using the same laboratory process as hospitals do with blood.
Buccal Swab Test
The method for collecting DNA samples for paternity is through a buccal swab test (also referred to as a DNA mouth swab test or a DNA cheek swab test). Using buccal swabs is just as reliable as using blood but far more convenient.
There are also many other advantages. The use of buccal swabs is non-invasive, and a much easier technique for the collection of DNA samples. Buccal swabs don’t require refrigeration like blood samples do, and they are good for several months after the collection has taken place.
DNA Hair Testing
Special specimens are sometimes used in place of a cheek swab sample. For example, a situation may exist in which the alleged father is deceased or otherwise not available to participate in the paternity testing. Special specimens are considered anything other than a buccal swab test used to extract DNA. Examples of this can be hair follicles (with root attached), toothbrush, q-tips, or tissue samples of any kind.
There are many challenges to DNA hair testing. First, the root of the hair follicle must be attached. DNA is not found within the hair shaft. Secondly, it cannot be guaranteed that a sufficient sample with good quality can be extracted. In a paternity test this could cause an inconclusive result. Thirdly, testing hair is an expensive process. Additional extraction techniques are performed for special specimen and often numerous attempts are made in an attempt to obtain DNA. The extraction cost is separate from the actual laboratory cost in this situation and can be quite an expensive alternative.
Though there are many DNA paternity testing procedures using buccal swabs is a much easier process as opposed to other sample types including hair. Be in the know, purchase a home paternity testing kit today.

Straightforward Programs In flocked swab – An Introduction

Huachenyang flocked swab: Unlike traditional fiber swab, it does not use a cushioned core, and it does not disperse and lock precious samples. In contrast to the traditional swab, the swab designed by iCleanwabs will float on the surface of the swab, thus completing rapid and thorough elution. ICleanwabs’vertical fiber structure is like a soft brush, which improves the collection rate of cell samples. The capillary effect between fiber bundles can help liquid samples to absorb strongly by hydraulic pressure, and the release rate is over 95%. Oral cells, dna, microorganisms, bacteria, viruses and other specimens are collected.

Vertical fiber structure, like a soft brush, improves the collection rate of cell samples. The capillary effect between fiber bundles can help the liquid sample to absorb strongly by hydraulic pressure. · Ergonomic and anatomical design improves patient comfort and sample collection efficiency. · Rapid, automatic and thorough elution to improve sensitivity.

Once iCleanwabs are in contact with the assay reagent, or placed in a buffer solution or transport matrix, the sample is released immediately, with a release of up to 95%. · Improving the quality of sample collection, such as velvet brush, can move cells quickly and effectively, and collect liquid by capillary action. Cells can be easily collected between fibers. · Quantitative transport: Absorption and movement between patients and test tubes remain quantitative, measurable and consistent. · The flocking swab technology obtained from technology and special benefits eventually opened the door to the process of liquid-based Microbiology and automated laboratories.

Introduction of how to use gene detection sampling box

Introduction of how to use gene detection sampling box

Step 1: After opening the packaging bag of the gene detection sampling box, remove one of the sealed sampling swabs and find the tear opening (the crown side of the sample, the paper prominent part) and tear it down.

The second step is to extend one end of the sampling crown of the gene detection sampling box into one side of the oral cavity wall, scrape the oral cavity wall with the sampling crown, scrape up and down, increase the scraping area as much as possible, and scrape more than 40 times. The sampling crown is made of medical non-woven material with a certain friction coefficient, which can make the oral mucosal epithelial exfoliated cells and part of saliva. The liquid is sucked on the surface of the sampling crown. After scraping, the sample swab can be handheld by a single hand. The sampling push rod is held against the thumb. The sampling crown is inserted into the sampling tube and the cap of the sampling tube is tightened. Another swab was used to scrape the contralateral oral wall.

Three: tear open cavity swab wrapping, take out exit cavity swab carefully (note: hand can not touch the swab part during the whole sampling process). Hold the handle, extend the swab into the left oral cavity, make the head of the swab fully contact the mucosa in the left cheek/upper and lower dental beds, and wipe it up and down with the force of brushing teeth. At the same time, rotate the swab, let the head of the swab fully contact the oral mucosa, and repeat this action by scraping up and down. The second swab was sampled at the mucosa of the right cheek/upper and lower dental beds by the same method.

  1. The swab with exfoliated cells in the mouth after sampling is put back into the collection tube in the clean ventilation place to complete sampling. Put the collection tube into the sample return bag, and then register your relevant information at the front label of the self-sealing bag: name, gender, age, collection date. The self-sealing bags with collection tubes and the inspection registration forms are sent to the sampling and testing company at room temperature.

Skills and characteristics of DNA flocking swab

First, what is flocking swab?

The top of the flocking swab is nylon fiber structure. The nylon fibers are deposited on the surface of the plastic rod in a certain direction by electrostatic field in order to form a brush layer, which is fully parallel to each other and perpendicular to the surface of the inner rod. DNA is collected through the brush head. At present, COPAN4N6 FLOQSwabs flocking swab has been patented in China, the United States, Japan and other countries and regions.

  1. What are the advantages of flocking swab in DNA collection?

Sample collection process: The unique structure at the top of flocking swab can greatly increase the number of samples collected.

Sample precipitation process: The brush layer structure can release almost all the collected samples.

  1. Why is flocking swab more advantageous for microDNA acquisition?

Traditional cotton swabs, because of the internal structure of cotton filament winding at the top of the swabs, make the samples dispersed and stayed in the fibers during sampling, resulting in lower efficiency of DNA precipitation and even false negative results of testing.

The unique structure at the top of the flocking swab can almost completely extract and precipitate a very small amount of DNA, so the flocking swab has more obvious advantages in microDNA acquisition.

  1. The principle of DNA collection and precipitation by flocking swab?

(1) By the directional wiping effect of the brush-like fibrous layer, the cell samples can be completely recovered.

(2) Since cell samples are concentrated near the surface of brush fibers, about 90% of absorbed samples can be released eventually.

(3) The capillary movement between nylon fibers at the top of the flocking swab forms a strong hydraulic pressure to absorb liquid or cell samples.

Characteristics and advantages of sampling swabs

Characteristics and advantages of sampling swabs

Sampling swab, also known as cervical sampling test, flocking cotton swab, is made up of nylon staple fibers and medical grade ABS plastic rods. The function of nylon staple fibers is like a soft brush, which can effectively improve the collection of cell materials. The capillary movement between fibers forms a strong hydraulic pressure, thus taking liquid samples. When the sample is close to the swab surface, it can be easily eluted. It can be used for bacteriological sample processing, virological cell culture, DFA test, rapid and direct test, enzyme immunoassay, polymerase chain reaction and molecular diagnosis-based detection.

Nylon flocking swabs are widely used and are ideal for bacteriological sample processing, virological cell culture, DFA testing, rapid and direct testing, enzyme immunoassay, polymerase chain reaction and molecular based diagnosis, as well as forensic identification. Similarly, flocking swabs can also be used for influenza, swine flu and avian influenza. Pharynx and throat sampling of respiratory viruses such as hand, foot and mouth.

Characteristics of Sampling Swabs

  1. Different preservation solutions were selected for different types of specimens.
  2. Each set of independent packaging in the big box is convenient to use.
  3. Paper-plastic packaging that is easy to sterilize in the world;
  4. Gamma ray sterilization to ensure sterility;

Advantages of Sampling Swabs

  1. Designed specifically for DNA micro-samples at crime scene, especially for sweat, semen, blood, dandruff, oral cells and other micro-samples with superior collection performance;
  2. The front end is pointed, which is suitable for the extraction of cells in the nail suture of the victim or suspect at the crime scene.
  3. The back end of the swab can be broken, which is beneficial to the automatic extraction workstation for sample extraction.
  4. The whole swab is packed in transparent plastic pipe to avoid biological pollution.
  5. It can adsorb trace samples quickly and has high release efficiency.

The collection system uses nylon flocking swab, which is harmless to microorganisms and can maximize the collection and release of specimens. A large number of clinical experiments show that nylon flocking swab has better collection and transportation effect on clinical microorganism specimens than ordinary sterile cotton swab. It is more advantageous for those specimens that can not be sent in time and placed for too long. It has unique jet implantation nylon fiber technology to increase the collection of specimens. The whole length of the swab is 15cm. The plastic rod has a unique breakable design. The villus texture can collect more target analytes. There is no sample residue. The process of sample processing is accelerated. The swab is sterilized and packed independently. The sterile swab is packed independently.
