Why use flocked swabs flocked swabs are made of nylon fiber flocking technology, the front end is coated with short nylon fibers fixed in a vertical manner, making the entire sampling swab sampling area without absorption holes, the sample will not be scattered and retained in the fibers, which is conducive to faster and more efficient elution. Traditional swabs do not completely collect and elute samples, while flocked swabs can elute 95% of samples. Therefore, the use of flocked swabs has great advantages for various sample collection applications.

What are the advantages of flocked swabs

①, sampling comfort, ease of use flocked swabs are now basically using "spray-on technology", through the electrostatic charge flocking process vertically attached to millions of nylon fibers on the head of the medical ABS swab rod. The vertical nylon fibers act like a soft brush, and the use of this soft brush during the sampling process allows the user to have no foreign body sensation. At the same time, the flocked swabs used in different parts of the body take different break points, and the rods use different thicknesses to make the softness different. For example, the upper end of the nasal swab is thinner and softer, and the break point is longer, which completely fits the ergonomic design.

②, flocked swab sample release is greater capillary action between nylon fiber bundles promotes strong hydraulic absorption of liquid samples. The sample stays on the surface, making elution easier. The collection and release volume is much greater than that of the traditional winding swab. Experimental studies have shown that the collection and release volume of flocked swabs can reach 95% of the sample, while the swab is only about 20%. Because most of the samples collected by swabs are easily intercepted in the fibrous matrix layer of the head when released, they are not easily released or released in very small amounts.

③. Flocked swabs are biocompatible and ideal for PCR work In order to limit damage to the sample and improve the accuracy of the assay, swabs are made of completely inert materials, while flocked swabs are PCR compatible and free of RNA enzymes and DNA enzymes.

Flocked swab operation method Today we take the sampling method of oropharyngeal swab as an example

First, ask the patient to sit down, then ask the patient to tilt his head back, open his mouth wide, and make an "ah~" sound;

②, the sampler fixed the patient's tongue with a tongue depressor, and used a flocked swab to cross the tongue root to the posterior pharyngeal wall and tonsillar fossa, lateral wall, etc;

③, repeatedly wipe 3~5 times to collect mucosal cells;

④、Take the swab out of the mouth slowly, put it into the sampling tube vertically, break the end of the swab, and screw the sampling tube tightly to avoid leakage

⑤. Send it to the laboratory for testing as soon as possible. Precautions in flocked swab sampling

①, swab into the sampling tube should be placed vertically, do not wipe to the mouth of the bottle to avoid contamination. When put into the transfer box should be disposed into, to avoid leakage of liquid

②, preferably sent on the day of sampling or sent to the laboratory for testing

③, before sending the test must verify that the specimen is consistent with the delivery sheet, the appearance of the sampling tube must be clearly written with the patient's name and basic information, there is no way to test the specimen without basic information;

④, the specimen must be submitted (or submitted electronically in advance) screening information form, the submission form and other materials, the material submitted should ensure that no contamination, do not put together with the specimen to be tested

Sampling swabs

Are nylon flocked swabs easy to break? When the health care provider scrapes the swab deep into the throat of your mouth and the tonsils next to the throat to remove epithelial cells, is the nylon flocked swab broken and left in the throat? If the swab rubs hard, will it scrape and will the broken fibers stay in the flesh? After watching the video above, you can think about it and try it out. Science Oh, what is nucleic acid sampling swab and raw material material nucleic acid sampling swab, or flocked swab, its head material is used nylon microfiber, small brush-like shape is ideal for rapid absorption of fluid samples from irregular surfaces, and can be collected to thoroughly release the sample into the culture fluid, soft bristles can also reduce the discomfort of the sampled person.

The handle of the sampling swab is generally made of polystyrene (or ABS) with a break point designed in the middle for easy folding and placing in a sealed bottle. Flocking: PA short flock (nylon short flock) or PET short flock (polyester short flock) Flocking adhesive: Flocking adhesive (polyacrylate emulsion adhesive)

Sampling rod material: HIPS (high impact polystyrene)
