QBC Autoread Plus: Features

The QBC Autoread Plus has a decade long proven track record of being extremely reliable in the world's harshest environments. From medical tents in Iraq and Afghanistan to research facilities in Antarctica, the Autoread Plus has proven that it can handle the worst conditions imaginable.

The Autoread Plus Dry Hematology System offers a durable, cost-effective option for conducting hematology testing in virtually any setting. The Autoread Plus System, which consists of a reader, a centrifuge, and an external printer, uses patented dry hematology technology to deliver a 9-parameter, 2 part differential.This results in many benefits for the user:

Eliminating Liquid Reagents

Unlike competing products, the Autoread uses no liquid reagents. That saves lab space for the user, since there is no need to store bottles of reagents. There is also less maintenance required, as there is no need for cleaning or replacing internal parts. The only waste products generated by the Autoread are the QBC tubes, which are easier to dispose of than dangerous biohazard reagent chemicals.

Durability and Portability

The Autoread System is the most durable CBC analyzer on the market, as its dry hematology technology and hard plastic frame make it suitable for conducting testing in even the harshest conditions. Because of the unique QBC dry reagent technology, the Autoread can be transported and quickly deliver results in any location. Setup time is minimal, as the Autoread is always ready to provide fast, accurate hematology analysis.

Easy to Use

Learning to use the Autoread is easy. After preparing a blood sample using a QBC tube, simply centrifuge the tube for five minutes at 12,000 RPM and then place it in the reader. Results will print out automatically using an attached printer. Office personnel can be easily trained to use the Autoread, making the most of any office's limited resources.

9-Count CBC

The Autoread measures nine important CBC hematological parameters from venous or capillary blood samples: hematocrit, hemoglobin, MCHC (mean corpuscular hemoglobin concentration), platelet count, white blood cell count, granulocyte count and percentage, and lymphocyte/monocyte count and percentage. Clinical trials have demonstrated that the accuracy and precision of the Autoread System correlate well to accepted standard methods.


The Autoread is exceptionally reliable. The system is permanently calibrated during manufacturing, so the user needs to only run a basic daily calibration check to verify satisfactory performance. Because of the unique QBC dry technology, the Autoread can deliver reliable results using only a fingerstick blood sample.

QBC Autoread Plus: Technology

The technology at the heart of the Autoread is a process known as Quantitative Buffy Coat (QBC) analysis.Dry Hematology Video

This process, is based on the physiological phenomenon in which the differing densities of blood components will cause them to separate into layers when centrifuged at a high rate of speed. Click on the image to the right to watch a video on the Dry Hematology technology.

QBC tubes, including the many varieties available for the Autoread, take advantage of this phenomenon in two ways. First, through the use of a small plastic float with the approximate density of platelets and white blood cells (the "buffy coat"), those usually small layers can be physically expanded for greater analysis. Second, a metachromatic acridine orange stain coating the inside of the tubes stain lymphocytes and monocytes green, platelets yellow, and granulocytes orange, making the difference between layers visible, even to the naked eye. Once a sample has been centrifuged, the Autoread utilizes a dual light source and optical detector to read the results of the test. Once complete, the Autoread prints the results to an attached external printer.

Controls and Diagnostics

Sample Collection and Analysis




Is the Autoread considered CLIA waived?
Currently, all of the QBC Systems are moderately complex.

Controls and Diagnostics

How often do I have to run external controls on the QBC Autoread Plus?
Traditional quality controls consists of running at least two levels of external control material each day of patient testing.

My controls arrived warm (ice packs were melted); can I still use the controls?
The controls may work in the short term, but may be prone to early degradation. If the controls are warm, a replacement set can be requested by calling Drucker Diagnostics Technical Support at +1-866-265-1486 (U.S. only).

Sample Collection and Analysis

What type of sample is required for QBC Autoread testing?
Whole blood samples collected from either a capillary fingerstick or a venous blood draw (EDTA purple top tube).

How much blood is required to test on the Autoread systems?
The amount of blood is dependent upon the tube type being used:

  • Accutube - 70µl
  • Standard Capillary - 60µl
  • Standard Venous - 111µl

What tube types can be used with the Autoread System?
Accutube, Standard Capillary, or Standard Venous.

What collection method should be used for the different tube types?
The collection method is dependent upon the tube type being used:

  • Accutube - fingerstick collection or venous blood (EDTA tube)
  • Standard Capillary - fingerstick collection
  • Standard Venous - venous blood (EDTA tube)

How long can a venous sample be stored prior to testing on the Autoread System?
This is dependent on each individual tube type. Check the tube package insert for each specification.

Can a sample be processed more than once on the Autoread?
Yes, once centrifuged, the QBC tubes can be analyzed more than one time. The tube must be stored in an upright position and is stable at room temperature for up to four hours. QBC tubes should NOT be centrifuged more than one time.

How can I get results from my QBC Autoread into other external systems (e.g., EMR, LIS, etc.)?
We recommend contacting Apex Healthware. Apex Healthware is a developer of affordable HL7 interfaces and laboratory information systems.


What printers are compatible with the QBC Autoread Plus?
Brother HL-5240, Brother HL-5250DN & Brother HL-5340D. Other printers may work with the systems if they use the Epson language (ESC/P2/LQ).

The Autoread ran the test but the results are not printing. Why?
Power off the printer and follow the instructions in the Operator's Manual for resetting the print format. Power on the printer and test the cal rod or a sample.

Can I reprint the results on the QBC Autoread?
If the tube is still in the instrument, press the "Next" button.


What causes a "Sample Error 20" or "Buffy Coat Unreadable" errors?
These errors are generally sample related. Ensure that venous samples are well mixed prior to loading the QBC Tube. Invert the venous tube 12-15 times prior to loading the tube or 5 minutes on a mechanical rotator. For capillary samples, proper collection technique is extremely important. Warming the finger, using a blade lancet, wiping off the first drop of blood, and refraining from excessive squeezing of the collection area will yield a good sample.  Certain illnesses and disease processes may contribute to these errors as well. If an illness or disease is thought to be the cause of the error, the patient should be tested via another method.

Contact Technical Support for any questions.

I am seeing discrepancies between the results on the QBC and the results from the reference lab. Why?
The results from two different CBC methodologies will rarely be exactly the same. Confirm that the results are from the same sample. If one set of results is from a capillary sample and the other set is from a venous sample, the results could vary significantly. If the results vary between multiple capillary or multiple venous samples, it could be due to differences in the times of collections technique.

If the results are from the same venous sample, remix the venous tube at least 12-15 inversions prior to sampling. Confirm that the test was performed within the acceptable time limit and that the venous sample was stored according to the manufacturer's recommendation.

Can I run Veterinary samples on the Autoread?
It is not recommended to run animal samples on the instruments designed for human testing. IDEXX has the QBC Veterinary instruments with the appropriate software and tubes for animal samples. Contact IDEXX at +1-800-248-2483.

What is CLIA?

CLIA is an acronym for Clinical Laboratory Improvement Amendments. It sets forth uniform quality standards for laboratories and applies to all entities that perform tests for health purposes on human specimens. CLIA requirements are based on the complexity of tests performed (waived, moderate, or high).

QBC hematology systems, such as the Autoread Plus, are considered moderate complexity test systems, and therefore must meet quality requirements for moderately complex testing.

Quality Requirements for Moderately Complex Tests

Written Procedure Manual

A procedure manual is a detailed sequence of activities showing how the test procedure is to be performed. It breaks down the test procedure one step at a time. You may utilize the Autoread Plus Operator's Manual as your procedure manual if it is your policy to do so. Please ensure personnel are informed that they must follow the procedure as stated in the Operator's manual for performing the test. The procedure must be approved and signed by the Laboratory Director.

Proficiency Testing

CLIA requires that you participate in a Proficiency Test Program. These programs monitor the performance of your test system. Participants will receive five unknown samples, three times per year. Samples are to be treated in the same manner as patient specimens. The results are evaluated and comparisons made to other laboratories within your Peer group; laboratories using the same analyzer and tube type. Below is a listing of Proficiency Test Providers and a chart percentage of QBC participants submitting results according to each provider.

American Proficiency Institute (API)

American Academy of Family Physician's (AAFP)

"Following the earthquake in (January 2010), our clinic lab was inundated with new patients. As a result, we needed a solution for quickly and effectively diagnosing anemia and other diseases. Someone told me about the Autoread Plus, and made a donation so that we could buy the system. I cannot begin to tell you the difference it is making in the accuracy and efficiency of our diagnostics. It is especially marvelous because there is not a tremendous amount of blood to be disposed of. Plus, our charts are such that the lab results can be nicely displayed."
Berry Rice, Director, Clinique Esperance et Vie, Terrier Rouge, Haiti


"With the QBC Autoread, we have been able to increase our overall lab productivity with only minimal maintenance and an impressive amount of convenience. The design of the system in terms of its size and portability is well-suited for rural district hospitals such as ours and enables us to think about not only hospital-based laboratory tests, but also the possibility of carrying our lab equipment to regional sites where their lab capacity may not be as robust as our own, thereby helping to create partnerships and increase health services more broadly throughout the region."
Dan Schwarz, Executive Director, Nyaya Health, Nepal


"The QBC Autoread Plus is a durable workhorse. We've used the unit for about 3 years in remote jungle locations and our newer stationary health clinic in the Bolivian Amazon. The unit provides valid and reliable results, and requires relatively low maintenance. It is also extremely user-friendly. Although we do not have a high patient volume (we average roughly 10 patients per day), the QBC Autoread Plus has outlasted nearly all of our other laboratory equipment. I highly recommend this product for analysis of hematocrit, hemoglobin, platelet count, and differential cell counts."
Michael Gurven, Integrative Anthropological Sciences, Unit Chair, University of California, Santa Barbara
