saliva kit

HCY Saliva DNA Collection kits CY-98000A is state of the art user-friendly DNA collection from donors at home, which is all-in-one system for collection, stabilization and transportation,storage of human DNA from superior saliva sample.

The median yield of DNA is 110 μg from a 2 mL saliva sample but the yield may range from a minimum of 15 μg to more than 300 μg. Even with the same donor, the yield may change from day to day. The median yield for any given study may depend on the population that is being sampled from.  

Most people take 2-5 minutes to deliver a saliva sample following steps 1 to 6.

1. Ringe mouth with warm water.

2. Unfold the kits, Spit into funnel until saliva volume (not bubbles) reaches the marked line-2ml.

disposable swab

Founded on June 2008, our products lincludes persnal care & labor protection product. While our mission is to be No.1 Chinese factory on swab, especially DNA collection swab. So from Mar 2012, we had cut off the old product & focused more on developing of disposable swab.

Our disposable swab including DNA collection swab, antiseptic CHG swab,antiseptic CHG applicator, clean swab are all sterized by γ ray.

Our new class 100,000 clean room & class 100,00 Laboratory built from 2016  and management of swab workshop conforms to GMP.In Jan 2018, Free sale certificate based on GMP is issued to us.

We had more than 22 aprroved patents on medical consumable & medical service. Now we are Chinese No. 1 factory on medical swab(DNA collection swab, antiseptic swab & clean swab), the only one with FDA/CE/GMP certificate.

virus swab

Many acute respiratory illness surveillance systems collect and test virus swab ( nasopharyngeal and/or oropharyngeal swab) specimens, yet there are few studies assessing the relative measures of performance for NP versus OP specimens.

We collected paired and OP swabs separately from pediatric and adult patients with influenza-like illness or severe acute respiratory illness. The specimens were tested for eight respiratory viruses by real-time reverse transcription-polymerase chain reaction (qRT-PCR). Positivity for a specific virus was defined as detection of viral nucleic acid in either swab.

The test result show that for respiratory disease surveillance programs using qRT-PCR that aim to maximize sensitivity for a large number of viruses, collecting combined NP and OP specimens would be the most effective approach.

oropharyngeal swab

Oropharyngeal swab is used to collect speciemen from throat for strep test.
It was used to sample the posterior oropharyngeal mucosal membrane. After swabbing, the swab applicator was cut off, and each absorbent swab was placed into a vial containing viral transport media.

Flocked swab is proved to be the best swab for specimen collection. It contains no inner fabric or other inner core to absorb the specimen), a larger amount of specimen is collected and retained. Not only does this provide for better sample yield, it also allows a more rapid and complete release of the sample into liquid media.

flocking swab

Flocking swab is an preferal choice for use with rapid diagnostic tests because of their ability to better collect cells or organisms at the collection site and rapid release of entire cells.

Flocking swab contain no inner fabric or other inner core to absorb the specimen , a larger amount of specimen is collected and retained. Not only does this provide for better sample yield, it also allows a more rapid and complete release of the sample into liquid media.

Flocking swab is available with pre-molded breakpoints, with printed indicators, so you can easily break the handle before attaching the cap to the vial.
