Device Description
The GEM® Hemochron™ 100 system is a battery-operated, point-of-care coagulation analyzer that represents the next generation platform of the predicate Hemochron™ Signature Elite microcoagulation system. The analyzer employs the same fundamental opto-mechanical clot detection technology and the same analytical algorithms used by the predicate device for calculating test results. The single-use test cartridges for Activated Whole Blood Clotting Time Plus (ACT+) or Low Range ACT (ACT-LR) assays are identical to the cartridges used by the predicate analyzer. Whole Blood Controls used on the GEM® Hemochron™ 100 system are identical to those used on the Hemochron™ Signature Elite. The system is intended for use only in clinical settings requiring point of care testing. ACT results for patient blood samples or liquid control material are displayed as ACT Celite-equivalent values (CEV) in seconds. The analyzer contains a test chamber which warms a test cartridge to the required temperature, and it performs all operations to measure the clotting time of a whole blood sample after it is placed in the test cartridge and the test is started by the operator. The user interface includes a color touch screen that displays various action keys and an external barcode scanner for reading Operator identification number (OID), Patient identification (PID) number and lot numbers and expiry dates of liquid quality controls (QC). The operator uses the touch screen to select a command, set software configurations or enter information. The GEM® Hemochron™ 100 system is POCT1-A2 compliant and has Wi-Fi and Ethernet networking capability. It has increased storage for 10,000 patient and QC records. ACT+ and ACT-LR cartridge labels are modified to include a 2D barcode that identifies test type, lot number and expiry date, which is readable by the internal camera. Quality control features such as designation of QC levels, tagging of test results with date and time, and entry of OID and PID numbers are included and are similar to the predicate device. The GEM® Hemochron™ 100 system is intended for use at the point of care professional healthcare environments such as the Cardiovascular Operating Room and Catheterization lab and is designed to perform its essential tasks of performing in-vitro diagnostic blood coagulation-time tests without the use of a network connection. The device contains an 802.11 interface which supports WPA2 encryption as well as EAP authentication framework. The device is able to connect to a Wireless Local Area Network (WLAN) via 802.11 b/g/n connections at 2.4 and 5 GHz. The communications interfaces supported by the device are utilized to configure or update the device software by supervisory staff before deployment to the intended use environment and in the reporting of test results to the Laboratory or Hospital Information Systems (LIS/HIS) by the clinical operators at the point of care. Test results are used directly at the point of care in aiding medical decision making, and the device's intended use is not reliant on the device's ability to transmit the information to the LIS/HIS. GEM® Hemochron™ 100 ACT+ cartridges are single-use disposable test devices with a well for application of liquid QC and whole blood samples. When a liquid QC or patient test is requested, the instrument prompts the Operator to insert a cartridge into the instrument. After the instrument warms the cartridge, it prompts the Operator to apply the sample into the sample well of the cartridge. The ACT+ test cartridge is a self-contained disposable test chamber preloaded with a dried preparation of silica, kaolin, phospholipid, stabilizers, and buffers that provide maximum activation as defined by clinical practice guidelines. Each cartridge is sealed in a foil pouch labeled with lot number and expiry date. Reagents in GEM® Hemochron™ 100 ACT+ cartridges (000GACT+) are identical in composition to those in the predicate Hemochron™ ACT+ cuvettes (JACT-LR). A 2D barcode added to the cartridge label identifies the test type, lot number and expiry date. This information is automatically read by the internal camera. Each box of GEM® Hemochron™ 100 ACT+ cartridges contain 45 pouches, each pouch containing one GEM® Hemochron™ 100 ACT+ cartridge and one desiccant packet. GEM® Hemochron™ cartridges are single-use disposable test devices with wells for application of samples. When a patient test or an LQC test is requested, the instrument prompts the Operator to insert a cartridge into the instrument. After the instrument warms the cartridge, it prompts the Operator to apply the sample into the sample well of the cartridge. Each GEM® Hemochron™ 100 ACT-LR cartridge is sealed in a foil pouch labeled with lot number and expiry date. The cartridge is a self-contained disposable test chamber preloaded with a dried preparation of Celite and silicon dioxide activators, potato dextrin, stabilizers, and buffers to provide maximum activation as defined by clinical practice guidelines. Reagents in GEM® Hemochron™ 100 ACT-LR cartridges (000GACT-LR) are identical in composition to those in the predicate Hemochron™ ACT-LR cuvettes (JACT-LR). A 2D barcode added to the cartridge label identifies the test type, lot number and expiry date. This information is automatically read by a new internal camera. Each box of GEM® Hemochron™ 100 ACT-LR cartridges contain 45 pouches, each pouch containing one GEM® Hemochron™ 100 ACT-LR cartridge and one desiccant. Blood coagulation instruments and assays should be quality controlled prior to and during routine use.

Trade NamePredicate DevicePredicate 510(k) NumberTrade NameDevice Description
GEM® Hemochron™ 100 SystemHemochron™ Signature Elite Microcoagulation SystemK193041GEM® Hemochron™ 100 SystemThe GEM® Hemochron™ 100 system is a battery-operated, point-of-care coagulation
analyzer that represents the next generation platform of the predicate Hemochron™ Signature
Elite microcoagulation system. The analyzer employs the same fundamental opto-mechanical
clot detection technology and the same analytical algorithms used by the predicate device for
calculating test results. The single-use test cartridges for Activated Whole Blood Clotting
Time Plus (ACT+) or Low Range ACT (ACT-LR) assays are identical to the cartridges used
by the predicate analyzer. Whole Blood Controls used on the GEM® Hemochron™ 100
system are identical to those used on the Hemochron™ Signature Elite. The system is
intended for use only in clinical settings requiring point of care testing. ACT results for
patient blood samples or liquid control material are displayed as ACT Celite-equivalent
values (CEV) in seconds.
The analyzer contains a test chamber which warms a test cartridge to the required
temperature, and it performs all operations to measure the clotting time of a whole blood
sample after it is placed in the test cartridge and the test is started by the operator. The user
interface includes a color touch screen that displays various action keys and an external
barcode scanner for reading Operator identification number (OID), Patient identification
(PID) number and lot numbers and expiry dates of liquid quality controls (QC). The operator
uses the touch screen to select a command, set software configurations or enter information.
The GEM® Hemochron™ 100 system is POCT1-A2 compliant and has Wi-Fi and Ethernet
networking capability. It has increased storage for 10,000 patient and QC records. ACT+ and
ACT-LR cartridge labels are modified to include a 2D barcode that identifies test type, lot
number and expiry date, which is readable by the internal camera. Quality control features
such as designation of QC levels, tagging of test results with date and time, and entry of OID
and PID numbers are included and are similar to the predicate device.
The GEM® Hemochron™ 100 system is intended for use at the point of care professional
healthcare environments such as the Cardiovascular Operating Room and Catheterization lab
and is designed to perform its essential tasks of performing in-vitro diagnostic blood
coagulation-time tests without the use of a network connection. The device contains an
802.11 interface which supports WPA2 encryption as well as EAP authentication framework.
The device is able to connect to a Wireless Local Area Network (WLAN) via 802.11 b/g/n
connections at 2.4 and 5 GHz. The communications interfaces supported by the device are
utilized to configure or update the device software by supervisory staff before deployment to
the intended use environment and in the reporting of test results to the Laboratory or Hospital

high heparin doses frequently associated with
cardiac catheterization and cardiopulmonary
bypass surgery. The test is unaffected by
aprotinin. The ACT+ is not sensitive to very
low levels of heparin such as those encountered
in critical care. The Hemochron Jr. APTT and
ACT-LR are available for monitoring low
levels of heparin.
The ACT+ test is performed on any
Hemochron Jr. model using a fresh whole
blood sample. Each instrument is portable and
intended for bedside use. The instrument is not
intended for home use.

(Activated Clotting Time Plus) test is a
quantitative assay for monitoring
anticoagulation with moderate to high
unfractionated heparin (UFH) doses in fresh
whole blood samples. This test is intended for
monitoring UFH administered during
cardiovascular surgery and cardiac ablation
procedures. The GEM® Hemochron™ 100
