Full Blood Count (FBC) analysis. It not only gives the value of haemoglobin, but also gives valuable indices such as MCV, MCH and MCHC, WBC and platelet count. A combination of FBC, blood film and retculocyte count should give sufficient information to direct you to the next set of investigations (eg. haematinics, Hb electrophoresis, haemolysis screen, bone marrow examination etc. to establish the diagnosis.

HemaApp measures hemoglobin levels and screens for anemia non-invasively by illuminating the patient’s finger with a smartphone’s camera flash.

ToucHb is a completely non-invasive (no blood!), portable, instant and cost-effective (affordable!) hemoglobin screening device to diagnose and monitor anemia in rural areas in developing countries.
If Dr. Gebre needs of the "best" technology for the screening of anemia I agree completely with Prof. Muttuswamy: the photometric measurement of hemoglobin is available on any haematology analyser. Among these, even the smaller ones provide additional information such as RBC count, Wintrobe's indices as well as a three population count of leukocytes. New applications could be the future but now these have not EBM
The study of a patient with anemia begins with the interrogation, physical examination and basic laboratory tests, namely: complete blood count with hematimetric indices, re¬cuento reticulocyte and platelet counts, profile iron (serum iron, transferrinemia, saturation transferrin and ferritin), erythrocyte sedimentation rate, liver function, renal function, thyroid function, serum LDH and haptoglobin.

That is realy good answer, I agree with Dr Juan Carlos Otaso,if you are good MD.
I agree with many answers but the original questiion was "the best SCREENING test" not the diagnostica iter in anemias. So, the best SCREENING test for anaemias is the photometric measurement of haemoglobin
I fully agree with the above comment from Antonio La Giola : hemoglobin is the definitely screening test for anemia, since definition of anemia is based on the hemoglobin concentration in peripheral blood (g/dl). However, I would have add the RDW index : its increase is the first manifestation of dyserythropoiesis (a general feature of anemia related to quantitative or qualitative red cell production disorders) and it often precede the decrease of hemoglobin.
Red blood cells Distribution Width (RDW) describe the anisocytosis of RBC population with three different formula (or definitions): i. RDWcv = [1ST (fL)/MCV]x100 is the ratio between the standard deviation of Mean Cellular Volume (MCV) and MCV. ii. RDWSD is the value (in fL) of the width of the distribution curve (histogram) corresponding to 20% of the total height. iii. MATH-1SD (in fL) is the mathematical correction of RDWcv with the following formula: [RDWCV(%)xMCV] /100. All different RDW suffer a lack of standardization that is technology and methodology related. In addition, some pre-analytical condition such as the time between blood collection and cellular counting, the type of anticoagulant solution and other must be considered because these interfere with the accuracy and repeatability of results. So, despite the theoretical purpose for RDW use, its clinical relevance is not unanimously accepted
