BETTER CLINICAL DECI SIONS
Loss-to-follow-up has consequences far
greater than the health of the individual patient. It
wastes precious resources and exacerbates the HIV/
AIDS crisis – increasing the chance of drug-resistant
strains of infection and hampering efforts to reduce
mother-to-child transmission of HIV. However, there
is a simple, cost-effective way to reduce loss-tofollow-up and improve health outcomes: the PointCare NOW system.
No more logistical headaches sending samples
to an off-site lab. No more waiting days or weeks
only to find that the blood sample is damaged, the
patient is impossible to locate, or she is too sick to
return to the clinic. With one sample, one system, one
visit, and in just eight minutes, the PointCare NOW
system gives you the essential information you need
to make clinical decisions.
The system performs all data analysis automatically – there’s no manual gating or interpretation of
There is much more to proper management of
HIV/AIDS patients than a regular evaluation of
T-cell status. It requires assessment, diagnosis,
and treatment of underlying health conditions.
That’s why the PointCare NOW system delivers
12 results total in one easy report:
• CD4/CD4%
• WBC
• Hemoglobin
• Lymphocyte, neutrophil, monocyte,
eosinophil (count and percent for all)
Is it time to initiate or change antiretroviral
therapy? Are there indicators of opportunistic
infections or parasites? The system’s CD4/CD4%
and hematology parameters give you greater
insight into the patient’s overall health – on the
spot, before he leaves the clinic – so you can
follow up and treat accordingly.

FDA- CL E A R E D P O IN TC A R E N O W – SY STEM SP ECIFIC ATIO NS
T EC H N O LO GY
The FDA-cleared PointCare NOW system achieves its breakthrough
performance in speed, simplicity, ease of use, and stability because
developers chose proven optical-measurement techniques for its core
technology and designed modular, injection-molded housings with
few moving parts to create a robust instrument ideal for challenging
environments and low-resource settings. The system has solid-state
electronics, and comes pre-calibrated from the factory, eliminating the
need for calibration by the operator.
The instrument platform combines two diagnostic systems in one
rugged, small-footprint unit that the user operates like a hematology
analyzer. Its fluidics system prevents operator contact with blood,
blood or fluid aerosols, and liquid waste, therefore eliminating the
costly need for a biosafety hood, which is mandatory for traditional
flow cytometry systems. The operator takes a capped phlebotomy
blood-sample tube and, with the cap still in place, inserts the tube into
a receiving slot in the instrument. There are also two additional slots
for reagent vials (sufficient for 20 samples). The instrument takes the
tube inside automatically, and the door closes and locks to prevent user
interaction with fluids. In a fully automated process, the system pierces
the cap, withdraws a precise aliquot of whole blood, and biochemically
processes the sample internally to give the results.
The door opens after eight minutes and the capped tube is returned
to the user after the results are displayed on the instrument screen. A
printer comes standard with every system to generate a paper record
of results. Waste generated during the test is decontaminated automatically and confined to a sealed container. Users are not exposed to the
biohazardous conditions encountered with standard methods of CD4
lymphocyte enumeration because operators do not remove the bloodtube cap, they do not pipette the sample and reagents into open tubes,
they do not vortex mix in an open tube, and there are no contaminated
reaction tubes and pipette tips for disposal.
The PointCare NOW system delivers 12 results in just eight minutes
in one easy report that can be printed and stored. It generates a white
cell differential, a total white cell count, and a hemoglobin concentration measurement, employing the same proven hematology technology
used in reference labs. The system also provides both absolute CD4
count and CD4%, expressed as a percent of total lymphocytes. This is
achieved by using a label to change the natural light scatter character-
P OIN TC A R E NOW CORREL ATI ON
istics of the CD4 subclass of lymphocytes to perform CD4 enumeration. The label consists of anti-CD4 antibodies coupled to nano-sized
gold particles. PointCare achieves a fast (< 1 minute) antibody reaction
time by adding a proprietary charge-neutralizing reagent to the whole
blood.
An axial light loss detector identifies any cell carrying the CD4
antigen on the basis of the granularity added by the colloidal gold
label. The system also employs a forward scatter detector in combination with the axial light loss detector to eliminate monocyte interference from the CD4 lymphocyte count and provide a differential
count for four classes of white blood cells (lymphocytes, monocytes,
neutrophils, and eosinophils). The optical system uses a long-lifetime
LED (light emitting diode) light source. LED light sources consume less
power and tend to be more stable than the lasers used in traditional
instruments, enabling long, service-free operation. Power consumption for the total system is approximately 60 watts on average, which
is much lower than the multi-kilowatt levels of power consumption
encountered with laboratory flow cytometers.
The PointCare NOW system provides internal and external measures
of quality control to ensure proper test performance for every sample.
Onboard controls automatically monitor and record more than 50
check points during every sample run. When appropriate, the system
flags any abnormality that may require further clinical intervention
from the laboratory or physician. This eliminates errors by the operator
in performing and reporting the test result, and reduces requirements
of clinician time to troubleshoot and interpret inconclusive reports.
Data-analysis software automatically identifies dot plot clusters for
cell enumeration, as well as abnormal clusters. When abnormal clusters
occur, and accurate cell enumeration is compromised, the software
alerts the user via a screen message, and does not report a result.
Operators are locked out of this software and cannot alter gates,
results, or flag messages, thus assuring the highest-quality results at all
times. External Daily Check controls are included with test kits at no
extra charge to ensure that the system pipettes, pumps, valves, and
optics are operating as specified. Users should run Daily Check controls
at the beginning of each workday before performing sample analysis.

The 2008/09 study at the National Public Health Laboratory of Haiti ran a CD4 Low Control 20 times in order to
evaluate repeatability. The CD4 count precision (CV) from this study was 13.5% .
After the release of PointCare NOW System Version 2 in 2010, PointCare conducted an internal study to reevaluate
precision for Low and Normal levels of CD4. Precision (CV) was ≤ 9.0% at the Low level, and ≤ 4.9% at the Normal level
when run 20 times each on two instruments.

“WE’RE A MILE AWAY FROM THE RAINFOREST
WHERE THERE ARE MOUNTAIN GORILL AS,
RIGHT ON THE BORDER BETWEEN UGANDA
AND THE DEMOCRATIC REPUBLIC OF CONGO.
There aren’t any tarmac roads here, there isn’t any public transport,
and lots of the patients live a day’s walk from the hospital. Many of
them live a subsistence existence and they can’t afford to get here.
So we drive to remote communities in our mobile HIV outreach
clinic vehicle equipped with the PointCare NOW system, and are
up-and-running testing patients within 20 minutes of arrival.
Before we had this machine, we’d see somebody in the clinic, then
we’d have to see them on another day to collect a blood sample.
We had a system of motorcycle riders that went ’round all of our
outreach sites on a particular day to collect samples. They would
have to ride for four hours along a muddy road through the Impenetrable Forest, to a laboratory on the other side, where we could get
them tested.
It took us three days to get the result, and we couldn’t get it back to
the patient until we saw them again two weeks later. Now, with this
simple piece of technology, we can deal with problems immediately.
We’re able to diagnose [AIDS] early, manage it early, and keep people
living with HIV fit and well... we’ve been able to change HIV from
being a death sentence into something that people can live with
and lead productive lives.”
