Lab Devices for Covid19 Testing

The Quest Diagnostics Lab-Developed Test (LDT)

The Lab-Developed test is an in vitro diagnostics procedure used to detect nucleic acid caused by the presence of SARS-CoV-2 in an individual’s respiratory specimen. 

Quest Diagnostics runs LDT tests on samples given by healthcare givers in a quest to determine if individuals under scrutiny have been attacked by COVID-19.

How the LDT works

First off, healthcare givers request for Quest supplies from Quest’s in-office phlebotomists. The healthcare caregivers then use the supplies to collect respiratory specimens from suspected individuals and send them to Quest Diagnostics labs. Medicals at Quest laboratories then run The LDT test to with a view to finding presence nucleic acid in the suspected COVID-19 specimen. 

Quest Diagnostics then sends the results to public health labs basing on existing guidelines. Unlike other COVID-19 testing centers, the Quest Diagnostic LDT doesn’t deal directly with the client under observation.

Key Developments Under the Lab Developed Test for COVID-19

  • At full capacity, the Quest Diagnostic labs will be carrying 25,000 a day. This will ease the burden on other COVID-19 testing centers
  • The test is only limited to testing for the presence of SARS-CoV-2 nucleic acid
  • Students being tested will receive a phone if the results are positive or inconclusive
  • Physicians can request for the LDT test using the code 39433.

Bronchial Lavage/Wash (BAL)

Have you ever heard about Bronchial lavage in the past? This is a minimally invasive procedure that involves the installation of sterile normal saline into sub-segment of the lungs. You will realize that it normally followed by the suction and the collection of the installation for later analysis. Here, a flexible bronchoscope is normally introduced into the sub-segment of the lung. It is worth noting that this procedure was introduced by American physicians in 1974. These physicians were known as Reynolds and Newball. Nowadays, it serves as a diagnostic tool for checking lower respiratory tract pathology. Also, this procedure has proved to have some therapeutic utility.

It is important to note that BAL is a diagnostic tool that can be used to accurately diagnose various infections out there. Also, it can be used to get material for culture and sensitivity. In most cases, this tool is normally preferred over other invasive techniques such as thoracoscopy and biopsies. For instance, if a disease such as Tuberculosis is on the rise, BAL will be able to sample the epithetical lining of the alveoli and thereby manage to detect tuberculosis more effectively. It is ideal for the early detection of many ailments.

Also, BAL can help in the diagnosis of fungal infections. This is because it has a sensitivity of 98%. You will note that it is almost equal to bronchial biopsy when it comes to sensitivity and specificity. Finally, BAL is a useful tool that can help you diagnose lung malignancy. From diagnosing bacterial pneumonia to lung malignancies, BAL has proved to be very effective in the past. For optimal performance, you need to have a backup power system. Consider this procedure today and you will be able to diagnose different respiratory infections that can hinder your productivity at the workplace or even at home. It is truly incredible.

Tracheal Aspirate/Sputum

Are you suffering from a respiratory system disorder? There are many factors that you should consider. You should consider undergoing a tracheal aspiration procedure. Here, your lungs and the lower airways will be samples for cytology and culture. This goes a long way in avoiding the potential contamination of the pharyngeal flora. Currently, diagnosing ventilator-associated pneumonia, is not very easy. It remains to be a big challenge for many doctors. Managing patients with this problem has also proved to be cumbersome as more resources are needed.

It is important to note that due to the increased technical skill and equipment needed, the collection of specimens other than sputum from the lower respiratory tract can be challenging for patients with more severe diseases. The tracheal aspirate which is one of the main methods of collecting a specimen from different patients involves obtaining tracheal secretions for culture and microbiological diagnosis of VAP. This procedure can readily be conducted at the bedside. The good news is that it is simple and is minimally invasive and inexpensive. This has proved to be very accurate and requires minimal investment.

Besides collecting this specimen this way, you can still use the test code 39433 (LDT test). This is a type of vitro diagnostic test which should purposely be carried out in one single lab. These tests can readily measure, or detect several analytes such as proteins, chemical compounds and so on in a certain sample. This is more ideal if you want to collect other respiratory specimens such as bronchial lavage/wash (BAL), nasopharyngeal aspirate/wash and so on. This has worked well for many patients in the past. If you have a respiratory disorder, you can consider using an LTD test to diagnose your problem. For optimal results, your clinic of choice should have a backup power system so that these tests can be carried out even when there is a blackout in that area. It is true to say that LDT tests are vital to the continued development of personalized medicine.

Roche Diagnostics Test for COVID-19

As opposed to lab-developed testing, the Roche Diagnostics test helps in decoding the SARS-CoV-2 virus genetic signature. The tests can be done from any reference laboratory or hospital across the US.

The results can be availed within four hours of completing the testing procedure. Besides this, the testing system can process up to nine hundred results within a duration of eight hours.

How the Roche Diagnostics Test work

  • A suspected COVID-19 case is referred to as a healthcare provider for further assessment. The healthcare giver should then get in touch with a medical professional who is at liberty to order for the COVID-19 test.
  • The medical professional collects swab samples from the suspected individual and proceeds to carry out the test within designated COVID-19 testing station that has the Roche Diagnostics testing system. 
  • The results are available within four hours of testing from where the individual can be placed under specialized care or released. 
  • Individual labs are at liberty to determine the cost of the test
  • This diagnostic system is only available is specific countries such as the United States.

Roche Diagnostics test comes along like a fast and effective procedure for testing for COVID-19 cases. Even then, it’s paramount that individuals observe precautionary measures that safeguard them from the SARS-CoV-2 virus. These measures range from healthy eating and avoiding crowded areas. It’s also prudent to source for enough food supplies and has some power system back up in preparation of the worst-case scenario such as a lockdown.

Benefits of Franek Backup Power For lab testing

Franek Technologies provides all in one power protection systems that include seamless automatic backup power. Its systems actively clean up power inconsistencies in voltage, frequency, and sinewave shape. This is extremely important when using a generator as the primary power source as generator power is notorious for damaging electronics with inconsistent frequency variations. Franek Technologies UPS systems also come into play when power is completely lost, as backup power is already online and synchronized, so there is not even a momentary loss of power experienced by the protected devices similar to how a dual power supply system works for a computer server only on a much larger scale.
