Sodium heparin anticoagulation of blood samples

Sodium heparin

Content:




[Product Name] Sodium heparin 

[Package Specification] Plastic bottle, 10g/bottle, 20g/bottle, 50g/bottle

[Product Standard] Q/WHDS 003-2016

[Product Performance] White amorphous powder, odorless, soluble in water, easy
to
absorb moisture, average molecular weight of 15,000, stable at room
temperature.
The potency of sodium heparin of our company is ≥150 IU/Mg, and the potency of
anhydrous sodium heparin is ≥ 160 IU/Mg. Other indexes were controlled
according
to sodium heparin standard.

 [Scope of application]

1. This product is applicable to the collection and anticoagulation of blood
samples for clinical biochemical examination and emergency biochemical
examination, and also applicable to the collection and anticoagulation of blood
samples for some hemorheology projects.  

2. The use of sodium heparin as an anticoagulant is recommended for the
determination of ion content in blood in clinical tests because it is the least
likely to interfere with the determination of other ions.  

3. This product is not a drug and cannot be used as an injection. Direct
injection
into human body and animals is prohibited.

[Precautions]

In order to ensure sufficient anti-coagulation of blood, it is necessary to mix
the blood upside down for 5-8 times as soon as possible after the completion of
blood collection, especially when the ambient temperature of blood collection
is
higher than 25℃, the mixing of blood and  sodium heparin must be sufficient
in
time, otherwise it is easy to cause blood coagulation or local coagulation.

Heparin anti-coagulation is not irreversible, so the test should be completed
within 6 hours after blood collection in heparin anti-coagulation test tube,
otherwise the test results may have errors.

Heparin may be involved in the metabolism of cell enzymes and ions, so the use
of
heparin may affect the test results. The dosage of heparin should ensure the
full
anti-coagulation of the whole and local samples, so as to ensure that most of
the
plasma indexes can be repeated within 6 hours, especially the sensitive indexes
such as AST, ALT, TBIL, DBIL and GGT.

Sodium heparin can be used at the same time with the separation gel.
Anticoagulant
effect, tube wall silicification, centrifugation conditions, separation gel
quality and so on will affect the blood separation effect. It is suggested that
high quality plasma samples can be obtained by using the blood separation gel
produced by our company.

It is recommended to use γ - ray irradiation at a dose of 8-25kgy. The
irradiation dose can be determined by the initial colony number.




[Warning and Prevention]

It is forbidden to use sodium heparin when it has impurities, abnormal smell,
color and expiration date.

When the sodium heparin solution appears turbid, it may be that the heparin
solution has been contaminated with bacteria or deteriorated, please do not
continue to use.

This product is a biological preparation, safe, non-toxic and harmless.
