Description
Technical field
The present invention relates to a kind of detection reagent, in particular in a kind of detection red blood cell the detection reagent of Hemoglobin F with
And the application of the detection reagent.
Background technique
In recent years, tire mother transfusion syndrome gradually caused the attention of ob-gyn, how to early diagnose out this hair
Emphasis disease concealment and the disease of serious consequence is easily caused to pay close attention to jointly as ob-gyn and clinical laboratory doctor.Due to normal
99.9% red blood cell contains hemoglobin A without Hemoglobin F in adult human body, and red blood cell contains blood red egg in fetus body
White F does not contain hemoglobin A, therefore can be by Hemoglobin F content in detection pregnant and lying-in women's body, between judging whether that generation tire is female
The case where blood transfusion.Known Hemoglobin F has stronger capacity antacid than hemoglobin A.Therefore, the Blood piece after fixation, sets
Held for some time in acidic buffer, the only red blood cell containing Hemoglobin F are not eluted, such as with eosin stains in scarlet
Color.Hemoglobin F acid elution test (K-B experiment) is fetus in the most common quantitative detection maternal blood circulation of current each hospital
Red blood cell number purpose method.Hemoglobin is carried out according to the method for " national clinical examination operating instruction " (third edition) defined
F acid elution test finds influence of this method result vulnerable to external factors such as temperature, manual operation factors, and when testing
Between it is longer.And this law is ineffective for the red blood cell elution without containing Hemoglobin F, causes to judge whether red blood cell contains
The differentiation of Hemoglobin F result is unobvious, and as a result accuracy is poor.
Summary of the invention
The purpose of the present invention is to provide a kind of detection reagents of Hemoglobin F in new detection red blood cell, on solving
State the problem of proposing in background technique.
To achieve the above object, the invention provides the following technical scheme:
The detection reagent of Hemoglobin F in a kind of detection red blood cell, including acidic effluent liquid and dyeing liquor；The acidity is washed
De- liquid is prepared by following raw material: 25% hydrochloric acid solution, hematoxylin solid, ferric trichloride solid, 95% ethanol solution, distilled water；
The dyeing liquor is prepared by following raw material: Yihong solid, distilled water；The acidic effluent liquid the preparation method is as follows: by 0.75
Gram hematoxylin solid is completely dissolved in 100 milliliter of 95% ethanol solution, mixes, and mixture A is made；2.4 grams of ferric trichlorides are consolidated
Body is completely dissolved in 2 milliliter of 25% hydrochloric acid solution, and distilled water is added later to 100 milliliters, mixes, mixture B is made；Mixture
A and mixture B is uniformly mixed according to 5: 1 ratio of volume ratio, obtains the acidic effluent liquid；The preparation method of the dyeing liquor
It is as follows: 1 gram of Yihong solid being completely dissolved in 100 milliliters of distilled water, mixes, obtains the dyeing liquor.
A kind of application of detection reagent as described above, its step are as follows: (1) Blood piece with 80% ethyl alcohol is fixed 5 minute,
The Blood piece fixed is placed in 40 DEG C -50 DEG C of the acidic effluent liquid and keeps the temperature 1 minute, washed to dry；It (2) will be after drying
Blood piece is dyed 1 minute with the dyeing liquor, is washed to dry；(3) Blood piece after drying is placed under microscope, is knitted referring to net red thin
Born of the same parents' method of counting counts percentage shared by Hemoglobin F positive red blood cell in 1000 red blood cells.
A kind of purposes of detection reagent as described above, the detection reagent be used to detect Hemoglobin F in red blood cell
In shared percentage.
Compared with prior art, the beneficial effects of the present invention are: detection reagent of the invention is to without containing Hemoglobin F
Red blood cell eluting power is stronger, so that whether there is or not Hemoglobin F fruiting areas to show clearly for red blood cell, improves observer and is easy visual fatigue
Situation, convenient for counting under microscope, count results accuracy is good.Also, Hemoglobin F is carried out with detection reagent of the invention
Acid elution test is substantially shorter test period, reduces operating procedure, while reducing extraneous factor probability of interference, convenient for experiment
Room quickly checks.
Detailed description of the invention
In order to illustrate more clearly of technical solution of the present invention, the present invention is made with reference to the accompanying drawings and examples further
Explanation.
Attached drawing 1 show the colored graph for detecting Hemoglobin F in maternal blood using the detection reagent of embodiment 1
Piece；
Attached drawing 2 show the colored graph for detecting Hemoglobin F in maternal blood using the detection reagent of embodiment 2
