| RED SKULL | The common serum tube red skull, blood collection does not contain
additives, for routine serum biochemical, blood bank and
serological test. |
| ORANGE RED SKULL | Fast serum tube orange red skull, blood in the coagulant,
accelerate the coagulation process. Rapid serum tube can make the
collection of blood coagulation in 5 minutes, apply to the
emergency department of serum series of tests. |
| YELLOW SKULL | The separation gel tube golden skull inert, blood adding inert
separation gel and coagulant. Samples were centrifuged and the
inert separation gel to liquid component of blood (serum or plasma)
and solid components (red cells, white blood cell, platelet,
fibrinogen, etc.) completely separate and complete accumulation in
the center of the tube and form a barrier, the specimens were
within 48 hours remained stable. The coagulant can activate the
coagulation mechanism and accelerate the coagulation process, which
is suitable for the emergency serum biochemical test. |
| GREEN SKULL | Heparin tube green skull, blood added with heparin. The effect of
heparin with antithrombin directly, can prolong the clotting time
of specimens. Suitable for red cell osmotic fragility test, blood
gas analysis, hematocrit test, erythrocyte sedimentation rate (ESR)
and sagacity and biochemical determination, not suitable for blood
coagulation test. Excess of heparin can cause aggregation of white
blood cells, which can not be used for white blood cell count.
Because it can make the blood film stained with light blue
background, it is not suitable for the classification of white
blood cells. |
| LIGHT GREEN SKULL | The plasma separation tube light green skull, the inert separation
tube with heparin lithium anticoagulant, reach the purpose of rapid
separation of plasma, is the best choice for the detection of
electrolyte and can also be used for conventional plasma
biochemical determinations and ICU emergency plasma biochemical
detection. Plasma samples can be directly on the machine and in the
frozen state to maintain stable for 48 hours. |
| PURPLE SKULL | 6. EDTA tube purple skull, ethylenediaminetetraacetic acid (EDTA,
molecular weight of 292) and its salts is a polyamino carboxylic
acid can effectively blood specimens of chelating calcium ions,
chelating calcium or calcium reaction sites to remove the block and
the termination of the endogenous or exogenous coagulation process,
thus preventing blood coagulation of blood specimen. Apply to blood
testing, does not apply to blood clotting test and platelet
function tests, nor does it apply to calcium ion, potassium ion,
sodium ion, iron ion, alkaline phosphatase, determination of
creatine kinase and leucine amino peptidase, suitable for PCR test. |
| LIGHT BLUE SKULL | sodium citrate coagulation test tube Blue Skull, sodium citrate and
calcium mainly through blood and anticoagulant effect. Applicable
to the coagulation experiment, the country is faced to order the
laboratory standardization committee (National Committee for
clinical laboratory standards, NCCLS recommended anticoagulant
concentration is 3.2% and 3.8% (quite 0.109mol/L 0.129mol/L),
anticoagulants and blood ratio is 1:9. |
| BLACK SKULL | Citric acid sodium sedimentation test tube black bonnet,
sedimentation test requirements of sodium citrate concentration is
3.2% (in 0.109mol/L) anticoagulant and blood ratio is 1:4. |
| GREY SKULL | Oxalic acid potassium / sodium fluoride grey bonnet. Sodium
fluoride is a weak effect of anticoagulants, often with potassium
oxalate or B sodium iodate with use, the proportion of sodium
fluoride, potassium oxalate 3 copies. 4 mg of the mixture can make
1 ml blood in 23 days not solidification and inhibit the
decomposition of sugar, it is determination of blood glucose
estimation good preservation agent and cannot be used for Urease
method determination of urea, also do not have method was applied
to the determination of alkaline phosphatase and amylase,
recommended for the detection of blood glucose. |
